Area and circumference of a Circle using C programming

 Q. Write a C program to find area and circumference of a circle.

Ans:

#include <stdio.h>

#define PI 3.14159

int main() {

    float radius, area, circumference;

    

    printf("Enter the radius of the circle: ");

    scanf("%f", &radius);

    

    // Calculate area and circumference using formulas

    area = PI * radius * radius;

    circumference = 2 * PI * radius;

    

    printf("Area of the circle is: %.2f\n", area);

    printf("Circumference of the circle is: %.2f\n", circumference);

    

    return 0;

}
