// CPP Program to Find the Area of Circle


#include <iostream>
#define PI 3.14

using namespace std ;

int main()
{
    float radius, area;

    cout << "Enter radius of circle :--> ";
    cin >> radius;

    area = PI * radius * radius;   //Formula to find the area of circle

    cout << "Area of circle is :--> " << area;

    return 0;
}

Output:

Enter radius of circle :--> 23

Area of circle is :--> 1661.06
