Question

The figure is a cone. It actually takes three cones just to make one cylinder. Find it’s volume.

Answer 1

Given data:

The given height of the cone is H=14 in.

The given radius of the cone is r=9 in.

The expression for the volume of the cone is,

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

Substitute the given values in the above expression.

`\begin{gathered} V=(1)/(3)\pi(9in)^2(14\text{ in)} \\ =378\pi in^3 \\ =1,187.522in^3 \end{gathered}`

Thus, the volume of the given cone is 1,187.522 cube-inches.
