Write a C++ program to calculate area of circle.

Program Code:

#include<iostream>

using namespace std;

int main()

{

int radius;

float area;

cout<< " Enter radius of circle : ";

cin>>radius;

cout<<endl;

area = 3.14 * radius * radius;

cout<<"Area of circle is equal to : "<<area;

return 0;

}

The program code is tested on www.jdoodle.com

Output:

Enter radius of circle : 23

Area of circle is equal to : 1661.06
