Question

The volume of a cylinder is ninety cubic meters. What is the volume of a cone with the same radius and the same height as the cylinder?
Answer

one hundred eighty cubic meters

thirty cubic meters

forty-five cubic meters

two hundred seventy cubic meters

Answer 1

The volume of a cylinder is (pi) r^2 (h).

So pi r^2 (h) = 90.

The volume of a cone is 1/3 (pi) r^2 (h).

You should be able to see that the volume of a cone is 1/3 the volume of a cylinder, therefore the the answer is 30.
