Question

Find the volume of a right circular cone that has a height of 3.5 ft and a base with a radius of 18.9 ft. Round your answer to the nearest tenth of a cubic foot.

Answer 1

1309.2

Explanation:

Answer 2

1309 ft³

Explanation:

Volume of cone=
`(1)/(3) \pi {r}^(2) h`

where r is the radius and h is the height of the cone.

Given that r= 18.9, h= 3.5,

Volume of cone

`= (1)/(3) (\pi)(18.9^(2) )(3.5) \\ = 416.745\pi \\ = 1309 \: ft^(3)`
