The cone in the diagram has the same height and base area as the prism. What is the ratio of the volume of the cone to the volume of the prism?

volume of cone/volume of prism = 1/2

volume of cone/volume of prism = 1/3

volume of cone/volume of prism = 2/3

volume of cone/volume of prism = 1

volume of cone/volume of prism = 3/2

The answer is volume of cone/volume of prism = 1/3. The volume of cone with height, h, and radius, r, is: V = 1/3πr^2h. If h = r, then V = 1/3πr^2 * r = V = 1/3πr^3. The volume of prism with height, h, and radius, r, is: V = πr^2h. If h = r, then V = πr^2 * r = V = πr^3. So, the volume of cone/volume of prism = 1/3πr^3 / πr^3 = 1/3.
