Question

A cone has a diameter of 4 inches and a height of 9 inches. Find the volume of the cone. Use 3.14 for \large \pi.

Answer 1

37.68 in.^3

Explanation:

diameter = 4 in.

radius = diameter/2 = 2 in.

height = 9 in.

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

`V = (1)/(3)(3.14)(2~in.)^2(9~in.)`

`V = (1)/(3)(3.14)(2~in.)^2(9~in.)`

`V = \blue{37.68~in.^3}`
