Exercise #3

Complete the following method double Planet::volumePlanet(): Return the volume of the target planet.

The Formula is as follow:

NOTE: Remember to constantly verify the Planet class to see if there anything that can help with the solution.

For example:

Test	Result
Planet p0("CIIC", 67211, true, 34.66, true, "AZGARD", "MILKYWAY"); cout << p0.volumePlanet() << endl;	21801.4
