# How to create C library functions

Write a library containing functions to compute the surface area and volume of a sphere. For a sphere of radius r, these values can be calculated using:

Surface Area = 4 Pi r squared (4 x Pie x r to the second power).

Volume = 4 Pi r cubed/3

Write a driver program to test your library.
