C++ Program to Calculate Area of Circle

Introduction

C++ Program to Calculate Area of Circle. I have used Dev-C++ IDE for debugging purpose. But you can use any C programming language compiler as per your compiler availability.

#include<iostream>
#define PI 3.141
using namespace std;

int main()
{
	float radius, area;
	cout << "Enter Radius: ";
	
	cin >> radius;
	area = PI * radius * radius;
	
	cout << area;
	return 0;
}
