IN PYTHON Write functions for the following: sphereArea (radius):
It returns the surface area of a sphere having the given radius. The formula is A = 4 pr2. sphereVolume(radius):
It returns the volume of a sphere having the given radius.
The formula is V = (4/3) pr3. Then write a main program that uses these functions to compute the surface area and volume of a sphere given the radius.
The program should prompt the user for the radius and then print out the surface area and volume.
