Question

Find the exact volume of a waffle ice cream cone with a 9​-in. diameter and a height of 15 inches.

Answer 1

The volume of a cone is:

`V_(cone)=(1)/(3)\pi r^2h,` where r is base's radius, h is cone's height.

If diameter is 9 in, then radius is 4.5 in and

`V_(cone)=(1)/(3)\pi (4.5)^2\cdot 15=101.25\pi.`

Answer:
`V_(cone)=101.25\pi.`
