Question

What is the volume of a cone (in cubic inches) with a radius of 2 inches and a height of 3 inches?

Use 3.14 for π. Round your answer to the nearest hundredth.

12.56 cubic inches
25.12 cubic inches
37.68 cubic inches
56.52 cubic inches

Answer 1

The formula of a volume of a cone:

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

We have:

r = 2 in and h = 3 in

substitute:

`V=(1)/(3)\pi\cdot2^2\cdot3=4\pi\ in^3\approx4\cdot3.14=12.56\ in^3`

Answer: 12.56 cubic inches
