Question

Please Help!!! I have 5 minutes left!!!!! The volume of a​ cone-shaped hole is 16 pi ft cubed . If the hole is 3 ft​ deep, what is the radius of the​ hole?

Answer 1

3.0699

Explanation:

V = pi*r^2*h

you have v and h and pi so you can get r

Answer 2

V = 1/3 • π • radius cubed • height

If the volume is is 16π and the height is 3, then 16π = 1/3 • π • r cubed • 3

16π ÷ (1/3 • π • 3) = 16

radius squared = 16 √16 = 4, so radius = 4

You can also check: 1/3 • r cubed • 3 = 16 The only value left to multiply is π
