Question: i have given you a program named funccallingfunccpp this program...

I have given you a program named FuncCallingFunc.cpp

This program has main() and eight functions

1. float areaCircle(float radiusIn);
2. float circumCircle(float radiusIn);
3. float areaSphere(float radiusIn);
4. float circumSphere(float radiusIn);
5. float volumeSphere(float radiusIn);
6. float areaCylinder(float radiusIn, float heightIn);
7. float volumeCylinder(float radiusIn, float heightIn);
8. float volumeCone(float radiusIn, float heightIn);

The challenge of this assignment is to reduce some redundant code by allowing functions to call other functions

Example

          1. the function   areaCircle(float) calculates the area of a given

              circle using the equation

area = PI * radius * radius

2. the function areaCylinder(float, float) calculates the surface area of a given cylinder using the equation

area = 2 * PI * radius * radius +

           height * PI * radius * 2

               By calling the function areaCircle(float) and

               circumCircle(float) the above equation can be shortened to

area = 2 * areaCircle(radius) +

            height * circumCircle( radius);

You just have to change the code in some functions to call other functions
