C Program to find Length of an Arc

Length of an arc formula

Length of an arc = (2* π * radius * central angle)/360

C Program to find the length of an arc

This C program gets radius and central angle as user inputs and computes the length of an arc.

#include<stdio.h>                                                                
                                                                                
void main()
{
    int radius, central_angle;
    float length=0;
    printf("\nFinds length of arc\n-------------------");
    printf("\nEnter radius: ");
    scanf("%d", &radius);
    printf("Enter center angle:");
    scanf("%d", ¢ral_angle);

    length = (2*3.14*radius*central_angle)/360;

    printf("Arc Length: %.2f", length);
}                                                                      
                                                                                  

$ cc length-of-arc.c 
$ ./a.out 

Finds length of arc
-------------------
Enter radius: 8
Enter center angle:45
Arc Length: 6.28
