Write a C program to find area of circle

In this tutorial we are going to write a C program to find area of circle.

Formula for Area of Circle = PI*R*R

where PI = 3.14

C Program to find area of circle :

#include<stdio.h>
int main() {
	float Radius, Area;
	
	printf("\nEnter Circle Radius : ");
	
	scanf("%f", &Radius);
	
	// value of PI is 3.14
	
	Area = 3.14 * Radius * Radius;
	
	printf("\nArea of Circle : %f", Area);
	
	return (0);
}

Output :

Enter Circle Radius : 7.5

Area of Circle : 176.625000
