Question

A cone-shaped pile of sawdust has a base diameter of 20 feet, and is 7 feet tall. Find the volume of the pile.

Answer 1

733.04 feet
`^3`

Explanation:

We are given the height and base diameter of a cone shaped pile.

We are to find the volume of this pile and we know the formula for the volume of the cone:

Volume of a cone =
`\pi r ^ 2 \frac {h} {3}`

Putting in the given values in the above formula:

Volume of cone-shaped pile =
`\pi (10)^2(7)/(3)` = 733.04 feet
`^3`.

Answer 2

Volume of cone shaped pile is 732.67 feet³.

Explanation:

A cone shaped pile of sawdust has a base of 20 feet diameter and height of 7 feet.

We have to calculate the volume of the pile.

As we know the formula to calculate the volume of a cone is
`(1)/(3)\pi r^(2)h.`

Therefore by putting these values in the formula we can get the answer

Volume of cone
`=(1)/(3)\pi ((20)/(2) )^(2)(7)`

`=(1)/(3)(3.14)(10)^(2)(7)`

= 732.67 cubic feet.

So the answer is 732.67 feet³.
