Question

A cylinder and a cone have the same diameter of 8 inches. The height of the cylinder is 5 inches. The height of the cone is 15 inches. Use pi equals 3.14. What is the relationship between the volume of the cylinder and the volume of the cone?

Answer 1

Cylinder: $v= \pi r^2h$
3.14 x 4^2 + 5 = 55.24

cone: $v= \pi r \frac{h}{3}$
3.14 x 4^2 + 15 = 251.2
