# C Program to Find Area And Circumference of Circle

Write a C program to find the area and circumference of a circle. The Circumference of the circle is the distance around the circle. The area of the Circle is π *r*r and the Circumstances of the Circle are 2*π*r. Calculate The Circumference of the Circle By Given Formula.

Circumference of a Circle = 2 * π * r.

Here PI (π) is a Greek Letter and r is a Radius (1/2 Of Diameter ). PI (π) = 3.141592653589793 Approx. It Is A Constant Value for more about Circumference Click Here

## C Program to Find Area And Circumference of Circle

``````#include <stdio.h>

int main()
{
/*write a c program to find area and circumference of circle*/
float PI = 3.14, area, ci;

printf("\nArea of Circle : %f ", area);

ci = 2 *PI * rad;
printf("\nCircumference of Circle : %f ", ci);

return (0);
}``````
