Question

A cone-shaped pile of sawdust has a base diameter of 28 feet, and is 11 feet tall. Find thevolume of the pile.

Answer 1

The diameter is given as 28 feet and height is 11 feet.

To find the radius of the feet,

`d=2r`
`28=2r`
`r=(28)/(2)=14`

To determine the volume of cone , use the formula .

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

Substitute the values in the formula.

`V=(1)/(3)*3.14*14*14*11`

`V=2256.6ft^3`

Hence the volume of pile is

`V=2256.6ft^3`
