The height of the pyramid in the diagram is three times the radius of the cone. The base area of the pyramid is the same as the base area of the cone. What is the expression for the volume of the pyramid in terms of the radius r of the cone?

V = πr2

V = 13πr2

V = 2πr2

V = 13πr3 (wrong)

V = 3πr3
