C Program to find Area of a Sector

Area of a Sector formula

Area of a Sector = (π * radius * radius * central angle)/360

C Program to find the area of sector

This C program gets radius and central angle as user inputs and computes the area of a sector.

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

    area = (3.14*radius*radius*central_angle)/360;

    printf("Area of Sector: %.2f", area);
}
                                                                       
                                                                                  

$ cc area-of-sector.c 
$ ./a.out
