for the 12m^3 it should be 12pim^3

volume of cone is: \[V={1\over3}\pi r^2 h\] we have V=12m^3 r = (6/2)=3m find h = ?

How? none of the options are right

because how i got it was right it was 4 and i did that by doing 1/3*3^2 and got 3 and the only one that would get me to 12 was 4 because 3*4= 12

what happened to the \(\pi\)

the question must have volume as \(12\pi\,{\rm m^3}\)

Divied 3 In 12 your answer is 4

you could use pythagoras' theorem to work out the height btw...cause it is a right angled triangle.

oh yeah now i remember lol this home schooling thing has kinda gottin my mind going a lil slow lol

you could also substitute values into the formula and solve for h, which is the preferred method

are you still sure the question does not have a "pi" in there?

didn't @Skittles10412 write that 'for the 12 m^3 it should be 12pi m^3' at the top of the page?

yeah im positive i finished the questions and i got 4m

Skittles10412Best ResponseYou've already chosen the best response.3
yeah i had to retype it to make sure that people who were going to help me knew that it was 12pi m^3 not 12m^3

yup and than you to every one who helped me :)

volume of cone = (1/3)(pi) x r^2 x h (pi) = 3.14159265359 6/2 = 3 12(pi) = (1/3)(pi) x 3^2 x h 12(pi) x 3 = (1/3 x 3/1) (pi) x 3^2 x h 36(pi) = (pi) x 3^2 x h 36(pi) = (pi) x 9 x h 36(pi)/(pi) = (pi)/(pi) x 9 x h 36 = 9 x h 36/9 = 9/9 x h 4 = h Answer = a) 4 m
