Best ResponseYou've already chosen the best response.0You know that the Surface Area equation of a cylinder right? which is:\[SA = 2\pi r^2 + 2\pi r H\] and the volume is : \[V = \pi r^2 H\] Perimeter is : \[P = 2\pi R\] all you have to do is find a relationship between all of them and you'll be able to figure out the height, perimeter and SA , so you'll get : Notice that the volume is = pi r ^2 h and the perimeter is = 2pi r so the SA can be written as : \[SA = 2(340)H + PH\]

Best ResponseYou've already chosen the best response.0are you sure that that's the only given?

Best ResponseYou've already chosen the best response.0yep i am givin x 1a2 i think that is the radious and i have to find all of those for numbers 112

Best ResponseYou've already chosen the best response.0you need more given, I doubt that the only given is the volume lol

Best ResponseYou've already chosen the best response.0ok so the whole thing is a project we have to figure out what is best for making a box..we are given x values 112 and the volume of 340 cubic inches 112 i believe are the radices

Best ResponseYou've already chosen the best response.0i need to find the hight. the surface aria..and the perimeter of a cylinder

anonymous

Best ResponseYou've already chosen the best response.0Alright, pick one of the radiuses and plug it in the Volume's equation to find H :) see if the number makes sense.

Best ResponseYou've already chosen the best response.0ok so i take piXr squared and get the hight?

Best ResponseYou've already chosen the best response.0for example .3.14X1 squared?

anonymous

Best ResponseYou've already chosen the best response.0V = pi r^2 H , you can plug in any value or R, then find H, and after finding H you can plug it in the perimeter, and when you find the perimeter you'll be able to find the SA, the new equation that I have wrote up there ^_^

Best ResponseYou've already chosen the best response.0as far as I can go lol, since I don't have enough given

anonymous

Best ResponseYou've already chosen the best response.0im not getting how you find h when you need it in the equation

anonymous

Best ResponseYou've already chosen the best response.0alright, we have the volume right? :)

anonymous

Best ResponseYou've already chosen the best response.0you have values of x, which are considered as the radius right?

anonymous

Best ResponseYou've already chosen the best response.0so you can take R = 4 for example and plug it in the following equation:\[V = \pi r^2h\] so we have R and V, we can solve for H, right?

Best ResponseYou've already chosen the best response.0lol, are you getting the idea now? :)

Best ResponseYou've already chosen the best response.0\[340=\pi(4) squared ?\]

anonymous

Best ResponseYou've already chosen the best response.0actually it's :\[H = (340)/(8\pi)\] and calculate it, that ofcourse if you choose your radius to be 4 ^_^ clear?

anonymous

Best ResponseYou've already chosen the best response.0wait it's 32 pi instead of 8 pi I forgot to square it lol!

anonymous

Best ResponseYou've already chosen the best response.0ok so i take x=340/r is this correct...if not i give up for the night and am going to bed..i am sure i am making this 100X harder than it actually is

anonymous

Best ResponseYou've already chosen the best response.0and that will give me the hight ?

anonymous

Best ResponseYou've already chosen the best response.0don't give up lol, alright, let's try once more! WE have x values, right?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0yes those values= the radius...so if the virst x value is 1 how do i get the hight?

anonymous

Best ResponseYou've already chosen the best response.0it's simple, just take your time and concentrate with me

anonymous

Best ResponseYou've already chosen the best response.0Okay so x = r = 1 we have given: R = 1 V = 340 find H= ?

anonymous

Best ResponseYou've already chosen the best response.0yep thats what i need to do...now how?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0The equation is : \[V = \pi r^2 h\]

anonymous

Best ResponseYou've already chosen the best response.0plug in the given in the equation and solve for H : 340 = pi (1)^2 H H = 340/pi H = 108.23 in ^_^

anonymous

Best ResponseYou've already chosen the best response.0we have found the height now :)

anonymous

Best ResponseYou've already chosen the best response.0now we need to find the perimeter right?

anonymous

Best ResponseYou've already chosen the best response.0are you following me lol? =P wakey wakey~

anonymous

Best ResponseYou've already chosen the best response.0ok so the hight for a radios of 1 is 108.2 correct

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0now, we can find the perimeter right? The equation is : P = 2pi R we have R = 1, solve :)

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ok so i take \[2piX(1)squared\]

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0lol no, the equation is :\[P = 2 \pi R\] substitute R in the equation and you'll get P ^_^

anonymous

Best ResponseYou've already chosen the best response.0lol yeah , that's right :)

anonymous

Best ResponseYou've already chosen the best response.0now, we can find the SA right?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0The equation is :\[SA = 2\pi r^2 + 2\pi r h\] we have R = 1 and H = 108.2 substitute the given and solve ^_^

anonymous

Best ResponseYou've already chosen the best response.0you have solved the question using R = 1 ^_^ did you get the idea now? :)

anonymous

Best ResponseYou've already chosen the best response.0ok let me make sure i can get this for 2 now and then ill let you go..if you dont mind

anonymous

Best ResponseYou've already chosen the best response.0alright, it's the same idea blackford, but different values for R ^_^, good morning andy

anonymous

Best ResponseYou've already chosen the best response.0same way of solving , good luck! ^_^

anonymous

Best ResponseYou've already chosen the best response.0the hight with a radios of 2

anonymous

Best ResponseYou've already chosen the best response.0hmm it should be 27.06 (340)/(4pi) = H H = 27.06 in

anonymous

Best ResponseYou've already chosen the best response.0and andy going quite lol

anonymous

Best ResponseYou've already chosen the best response.0oops i see i think..i just realized you want h by itself

anonymous

Best ResponseYou've already chosen the best response.0yep ^_^ since we want to find it

anonymous

Best ResponseYou've already chosen the best response.0ok for a R of 3 i got 12.02 for the hight..correct?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ok i think i am getting it now

anonymous

Best ResponseYou've already chosen the best response.0you got the idea now :)

anonymous

Best ResponseYou've already chosen the best response.0you can proceed on your own right?

Best ResponseYou've already chosen the best response.0now for a square pyramid. this time i need the hight,perimeter, SA, and lateral aria

anonymous

Best ResponseYou've already chosen the best response.0volume still 340 and same x values 112

anonymous

Best ResponseYou've already chosen the best response.0All you have to do is write down the new equations for the square pyramid

anonymous

Best ResponseYou've already chosen the best response.0i think that x= base length now

anonymous

Best ResponseYou've already chosen the best response.0Volume is : \[V = (b^2h)/3\] Surface Area is : \[SA = 2bs + b^2\] and perimeter : \[P = (\SB)(1/2)(l)\] find the relationship and solve ^_^ same idea as the previous one :)

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0oh and the lateral area is = PL/2 where P = perimeter and L = slant height ^_^

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ok so 340=1squared(h)/3

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0oh yeah i want the slant hight not lateral aria

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0so \[340=1^2(h).....340=1/3 =.33 340/.33..correct or no\]

anonymous

Best ResponseYou've already chosen the best response.0lol, I see what's your problem, you got the idea, but have trouble with calculation, take your time answering the questions :) step at a time ^_^
