Write a program to enter radius of circle and print perimeter if its radius is less than 5 otherwise print area of circle

Perimeter of circle (C) = 2*pi*r

Area of circle (A) = pi*r*r

#include<stdio.h>

void main()

{

  int r;

  float pi=3.14, c, a;

  printf("Enter radius of circle");

  scanf("%d", &r);

  if(r>5)

   {

      c = 2*pi*r;

      printf("Circumference of circle = %f", c);

    }

 else

     {

      a = pi*r*r ;

      printf("Area of circle = %f", a);

    }

  }
