Question

What is the area of the base of the cone below? Round the answer to the nearest tenth if necessary.

Answer 1

19.5

Explanation:

Answer 2

Area of the base is 19.5 unit square.

Explanation:

The volume of the cone is given as = 52 cubic inches

Height or h = 8 inches

Volume of the cone is given as :
`\pi r^(2) (h)/(3)`

`52=3.14* r^(2) *(8)/(3)`

`52= r^(2) * 8.37`

`r^(2) =6.212`

r = 2.492 inches

Now, area of the base is given as
`\pi r^(2)` because it is a circle.

Area =
`3.14*2.492*2.492`

= 19.499 ≈ 19.5 unit square.
