Calculate Area and Circumference of Circle in C

C Program to find the Area and Circumference of the Circle from the given radius.

Source code :

#include<stdio.h>

#define PI 3.14159265358979323846

int main(){

int radius = 10; // Change the radius
float area,circumference;


area = PI * radius * radius;
circumference = 2 * PI * radius;

printf("Given Radius : %d
Area : %f
Circumference : %f",radius,area,circumference);

return 0;

}

Output :

Given Radius : 10
Area : 314.159271
Circumference : 62.831852

Output :
