Calculating Radius, Diameter, Circumference , Area and Length of a Circle

Write a program that asks a user to input the radius and degree of a circle, the program reads it in and calculates: The radius, Diameter, Circumference, Area and Length of a circle.

SOLUTION

#include<stdio.h>

#include<stdlib.h>

/*function main begins program execution */

int main(void)

{

/*Initialization phase */

    int radius;  // radius to be entered by the user

    int degree; // degree to be entered by the user

 /*Processing phase */

    printf("Insert radius and degree of the circle:"); /*Prompting for input */

    scanf("%d%d", &radius, &degree);  /*reading radius and degree from user */

    printf("Radius is:%f\n", radius*1.0); /*displaying result 

    printf("Diameter is:%f\n", radius*2.0); /*displaying result 

    printf("Circumference is :%f\n", radius*2*3.1415); /*displaying result 

    printf("Area is:%f\n", radius*radius*3.1415); /*displaying result 

    printf("Length is:%f\n",radius*2*3.1415*degree/360); /*displaying result 

    return 0; /* indicates that program ended successfully */ 

}
