C++ Program to calculate the volume and surface of the cylinder.

Let see the program to calculate the volume and surface of the cylinder.


Example:

Formula: 

Cylinder


/* to calculate the volume of the cylinder. */
#include <iostream>

using namespace std;
int main()
{
    double radius,height,volume;

    cout<<"Enter radius of cylinder :";
    cin>>radius;
    cout<<"Enter height of cylinder :";
    cin>>height;
    volume=(22/7)*radius*radius*height;
    cout<<"Volume of cylinder = "<<volume<<" units."<<endl;

    return 0;
}

Output:


Enter radius of cylinder :5.7
Enter height of cylinder :9.3

Volume of cylinder = 906.471 units.


/* to calculate the surface of the cylinder. */
#include <iostream>

using namespace std;
int main()
{
    float radius,height,volume;

    cout<<"Enter radius of cylinder :";
    cin>>radius;
    cout<<"Enter height of cylinder :";
    cin>>height;
    volume=2*(22/7)*radius*height+2*(22/7)*radius*radius;
    cout<<"surface of cylinder = "<<volume<<" sq. units."<<endl;

    return 0;
}

Output:


Enter radius of cylinder :2.4
Enter height of cylinder :5.7

surface of cylinder = 116.64 sq. units.
