Question

The volume of a cone is 50 pi cubic feet. Its height is 6 feet. In feet, what is the radius of the cone? Round the answer to the nearest tenth.

Answer 1

5ft

Explanation:

I did the test

Answer 2

The radius of the cone is
`5\ ft`

Explanation:

we know that

The volume of a cone is equal to

`V=(1)/(3)\pi r^(2)h`

In this problem we have

`V=50\pi\ ft^(3)`

`h=6\ ft`

substitute in the formula and solve for r

`50\pi=(1)/(3)\pi r^(2)(6)`

Simplify

`25=r^(2)`

square root both sides

`r=5\ ft`
