Create aderived class for Cone called PartialCone. Add a second radius variable with scope specific to this class (because the top and bottom radii of a partial cone are different). Redefine the set_volume function.

The formula for the volume of a partial/truncated cone is:

• V = h * (PI / 3) * (R² + (R * r) + r² )


• V = volume


• R = base radius


• r = top surface radius
