A Program to Find the Area of a Circle
In this example, we are giving a program to find the area of a circle. The rule of finding the area of a circle is: A = πr2.
Program to find the area of a circle:
#include <stdio.h>#include <stdlib.h>#include <math.h>int main() {float pie, r, area;pie = 3.14;printf("Enter the value of radius: ");scanf("%f",&r);area = 3.14 * pow(r,2);printf("Area of circle: %.2f", area);return 0;}
Output:
Enter the value of radius: 3 Area of circle: 28.26
