Best ResponseYou've already chosen the best response.02(22/7)r = (44/7)(15)=660/7feet^2 this is the bottem of the container (ill make it into decimals later)

Best ResponseYou've already chosen the best response.0that is circumference of the bottem. Now we'll find the area of the middle section of the silo by multiplying it by 40 to get (660/7)(40)=26400/7 its more accurate to wait till the very end to round it off but if your still in high school then i guess you can round it off to 2 dec one time

Best ResponseYou've already chosen the best response.0ok now to find the area of the bottem (22/7)r^2 (22/7)(15)^2 (22/7)(225) 4950/7

Best ResponseYou've already chosen the best response.0okay so, the circumference is 94.28?

anonymous

Best ResponseYou've already chosen the best response.0okay:) so the middle part is 3771.42, right?

anonymous

Best ResponseYou've already chosen the best response.0no its 3771.43 because 3771.428 is closer to 3771.43 than 3771.42

Best ResponseYou've already chosen the best response.0sorry :p so, on the 3rd explanation what do you mean by bottom?

anonymous

Best ResponseYou've already chosen the best response.0the bottom of the silo, in other words the circle with radius 15

Best ResponseYou've already chosen the best response.0with the circumference of 94.3?

anonymous

Best ResponseYou've already chosen the best response.0but make it two dec places not 1

Best ResponseYou've already chosen the best response.0okay. so do i need to do anythign wih that triangle above the silo??

Best ResponseYou've already chosen the best response.0for the area of the middle section dont use fractions then put 94.29x40 = 3771.6

Best ResponseYou've already chosen the best response.0yes you do were actually only half way through this question

Best ResponseYou've already chosen the best response.0and the area for the bottom is 4950/7 = 707.14

Best ResponseYou've already chosen the best response.0lol okay:) so now the pyramid thing. what ami supposed to do?

anonymous

Best ResponseYou've already chosen the best response.0for the cone at the top now this is just something u have to learn. A cone is also a semi circle and the 17feet is the radius of that semi circle

Best ResponseYou've already chosen the best response.0so (1/2)(22/7)r^2 (11/7)(17^2) (11/7)(289) 3179/7 454.14

anonymous

Best ResponseYou've already chosen the best response.0the area of the pyramid at the top (cone) which is 454.14feet^2

Best ResponseYou've already chosen the best response.0u understood wat i did?

anonymous

Best ResponseYou've already chosen the best response.0dw:1327636571579:dw so we find the area of the circle and then divide it by 2 using that formulae

anonymous

Best ResponseYou've already chosen the best response.0okay. :) so now we add both answers to get the whole thing, right?

Best ResponseYou've already chosen the best response.03? we have the bottom of silo and pyramid.

anonymous

Best ResponseYou've already chosen the best response.0also the middle section

Best ResponseYou've already chosen the best response.0where u got 454? and it is 3771.6

anonymous

Best ResponseYou've already chosen the best response.0sorryabout the .6:) i thought the 454 was the area of the pyramid?

anonymous

Best ResponseYou've already chosen the best response.0oh yes my bad and its 454.14 feet dont forget about the dec places

anonymous

Best ResponseYou've already chosen the best response.0and then we divide by 400?

anonymous

Best ResponseYou've already chosen the best response.0so 707.14+454.14+3771.6= 4932.88feet^2

anonymous

Best ResponseYou've already chosen the best response.0therefore to conclude this confusing and long question 4932.88/400= 12.3322 gallons
