Write a program in C that computes the area and circumference of a circle using functions. The program will ask the user to input the radius of the circle and it will display the area and circumference.

Program Flow

1. ask the user to enter the radius

2. read the radius

3.call (circle_area_func(float radius))

4. get returned value area

5. call (circle_circumference_func(float radius))

6. get returned value circumference

7. display area and circumference
