Question

Geometry! Please help!

A pile of sand in the shape of a cone has a diameter of 8 in. and a height of 5 in.

What is the volume of the cone?

Use 3.14 for π .

Enter your answer in the box as a decimal to the nearest cubic inch.

Answer 1

Answer:
`84\text{ in.}^3`

Explanation:

The volume of cone is given by :-

`V=(1)/(3)\pi r^2 h`, where r is radius and h is height of the cone.

Given: Diameter : 8 in.

Then Radius =
`(8)/(2)=4\ in.`

Height : 5 in.

Then , the volume of the cone will be :-

`V=(1)/(3)(3.14) (4)^2 (5)=83.73333333\approx84\text{ in.}^3`

Hence, the volume of the cone =
`84\text{ in.}^3`
