"A cone has the radius of 24 and its volume is 1,920 what is the volume of a similar cone with the radius of 18 Answers A.480 B.810 C.1,080 D.1,440" How do I find the height for the similar cone to get its volume?
Answered by Steve
since volume scales as the cube of the linear scale,

the new cone is scaled in every dimension to 3/4 the original cone. So, its volume is (3/4)^3 * 1920 = 810

Note that you don't need the height, just the relative scale factor.

1/3 pi r^2 h = 1920

1/3 pi (3/4 r)^2 (3/4 h) = 1920 * (3/4)^3
