Calculate the volume of a cylinder

Write a program in C++ to calculate the volume of a cylinder.

What is a cylinder?

There are many types of cylinders. This page describes the simplest shape, where a cylinder looks like a tube or can of soup, with two equally sized parallel circles at each end.

Cylinder Terminology

To calculate the volume of a cylinder, first need to understand some terms.

Radius - The radius is the distance from the center of the end circle to                  the end.

Pi - Pi is a special number used in circles. We use a                                        shortened version of Pi = 3.14. We also use the symbol π to refer             to the number pi in the equation.

Height - Cylinder height or length.

Volume of a Cylinder

There is a special formula for finding the volume of a cylinder. Volume indicates the amount of space occupied by the interior of the cylinder. Answers to questions about volume are always in cubic units.

Volume = πr²h

This is the same as 3.14 x radius x radius x height.

Sample Solution:

C++ Code :

#include <iostream>

using namespace std; 

    int main()

    {

    int rad1,hgt;

    float volcy;

     cout << "\n\n Calculate the volume of a cylinder :\n";

     cout << "-----------------------------------------\n";     

     cout<<" Input the radius of the cylinder : ";

     cin>>rad1;

    cout<<" Input the height of the cylinder : ";

    cin>>hgt;

    volcy=(3.14*rad1*rad1*hgt);

    cout<<" The volume of a cylinder is : "<< volcy << endl;

     cout << endl;

     return 0;

    }

Sample Output:

Calculate the volume of a cylinder :                                 

-----------------------------------------                             

 Input the radius of the cylinder : 6                                 

 Input the height of the cylinder : 8                                 

 The volume of a cylinder is : 904.32
