Code Implementation for C Program to Find Area of Circle

#include <stdio.h>

#include<conio.h>

int main() {

  float pie = 3.14;

  int radius;

  printf("Enter The Radius of Cicle:");

  scanf("%d",&radius);

  printf("The radius of the circle is %d\n" , radius);

  float area = (float)(pie* radius * radius);

  printf("The area of the given circle is %f", area);

  return 0;

}

Output

The radius of the circle is 10

The area of the given circle is 314.000000
