Write a program to find out the area of circle

   C PROGRAM TO FIND OUT AREA OF A 

                                CIRCLE

                                                    Best C programming app is Dev c++

To find the areaa of a circle we have to apply the formula given below:-

                               [   (pi*r*r)   ]

The program we will write as given below:-

#include<stdio.h>
int main()
{
float pi=3.1416,area;
int r;
printf("Enter the Radius:");
scanf("%d",&r);
area=pi*r*r;
printf("Area of the Circle is %f",area);
return 0;
}

OUTPUT:-

Enter the Radius:6
Area of the Circle is 113.097595
