Implement the following equation 3/4 x4 sin(45x) + 11/15 x3 cos(25 x) + 1/2 x2 tan(30 x) + 12x-1 + 9/ x^2 cos(108 x2 ) Where value of x will be 5. Make a program to find the diameter d=2r and area A=4r^2 of the sphere. Value of r should be defined by the user.

NOTE: programme should be in c language.
