To calculate area and circumference of any circle in C programming, you have to ask to the user to enter the radius of circle say r and make two variable for area and circumference each, place 3.14*r*r in area and 2*3.14*r in circumference, then display the result

C Programming Code to Calculate Area and Circumference of Circle

Following C program ask the user to enter the radius of the circle, to calculate and display the area and perimeter of the circle:

/* C Program - Calculate Area and Circumference of Circle */
		
#include<stdio.h>
#include<conio.h>
void main()
{
	clrscr();
	float r, area, circum;
	printf("Enter the radius of the circle :");
	scanf("%f",&r);
	area=3.14*r*r;
	circum=2*3.14*r;
	printf("Area of the circle = %f\nCircumference of the circle = %f\n",area,circum);
	getch();
}

When the above c program is compile and executed, it will produce the following result:
