The volume of a cone is 36π cubic units. What is the volume of a cylinder that has the same base area and the same height?

V_cone = 1/3 pi * r^2 * h

V_cylinder = pi*r^2*h

If you multiply the cone's volume by 3 then you get the cylinder's volume. They become the same formula

3 V_cone = pi r^2 h

Since the cone's volume is 36pi They cylinder's volume is 3*36pi = 108 pi
