Question

The cone to the right has a height of 11 in. and a volume of

103.62 in. Find the radius of the base.

Answer 1

2.99924 in

Explanation:

Volume of a cone

V = pi x r^2 x h/3

So to solve this problem you plug in the number we already have which is the volume and the height

103.62 = pi x r^2 x 11/3

28.26 = pi x r^2

28.26/pi = r^2

`\sqrt{(28.26)/(\pi ) }` = r ≈ 2.99924
