Today We Calculating the Volume of a Cylinder. Find the radius of the circular base. Either circle will do since they are the same size. Calculate the area of the circular base.

## C++ program to find volume of cube, cylinder, sphere by function overloading

#include<iostream> #include<conio.h> using namespace std; main() { float r,h,volume; const float pi=3.1417;cout<<"Enter the value of radius of the cylinder:"; cin>>r; cout<<"Enter the value of height of the cylinder:"; cin>>h; volume=pi*r*r*h;cout<<"Volume of the cylinder is="<<volume; getch(); }

**Output of Program**

Enter the value of radius of the cylinder:40 Enter the value of height of the cylinder:25 Volume of the cylinder is=125668
