Question

The volume of a cone is 62.8 cubic inches the height of the cone is 15 inches wha it's the radius of the cone my answer 8 inches

2 inches
4inches
8inches
9inches

Answer 1

\(\Large V_{cone} = \dfrac{1}{3} \pi r^2h\)

Answer 2

Plug in the given values and solve for r.

Answer 3

I don't get 8 inches.

Answer 4

Cone Volume = (π • r² • h) ÷ 3

3 * Volume / (PI * h) = r²
3 * 62.8 / (3.14159 * 15)

188.4 / 47.124 = r²

4 = r²

So r = ??

Answer 5

2 inches
