Question

The volume of a​ cone-shaped hole is 25 pi ft cubed . If the hole is 3 ft​ deep, what is the radius of the​ hole?

Answer 1

5ft

Explanation:

According to the scenario, computation of the given data are as follows,

Volume = 25π ft cubed

Depth = 3 ft

So, we can calculate the radius by using following formula,

V = 1/3 ×π ×radius squared×depth

25π = 1/3×π×radius squared ×3

Radius squared = 25

Radius = √25

Radius = 5 ft

Hence the radius of the hole is 5 ft.
