in this post we will learn how to write a C Program to find area and circumference of circle.

Area of Circle = PI * R * R 1

Circumference of Circle = 2 * PI * R

#include <stdio.h>

/* The simplest C Program to Calculate Area and Circumference of circle */

#include<stdio.h>

int main() {

  int radius;
  float PI = 3.14, area, circumference;

  printf("\nEnter radius of circle: ");
  scanf("%d", &radius);

  area = PI * radius * radius;
  printf("\nArea of circle : %f ", area);

  circumference = 2 * PI * radius;
  printf("\nCircumference : %f ", circumference);

  return (0);
}
/*

OUTPUT:

Enter radius of circle: 5

Area of circle : 78.500000
Circumference : 31.400002
