«
»

This is a C Program to find volume and surface area of sphere.

Problem Description

This C Program calculates the volume and surface area of sphere.

Problem Solution

The formula used in this program are Surface_area = 4 * Pi * r2, Volume = 4/3 * Pi * r3 where r is the radius of the sphere, Pi= 22/7

The C program is successfully compiled and run on a Linux system. The program output is also shown below.

/*
 * C Program to Find Volume and Surface Area of Sphere
 */
 #include <stdio.h>
#include <math.h>
 
int main()
{
 
    float radius;
    float surface_area, volume;
 
    printf("Enter radius of the sphere : \n");
    scanf("%f", &radius);
    surface_area =  4 * (22/7) * radius * radius;
    volume = (4.0/3) * (22/7) * radius * radius * radius;
    printf("Surface area of sphere is: %.3f", surface_area);
    printf("\n Volume of sphere is : %.3f", volume);
    return 0;
}
Program Explanation

In this C program, library function defined in <math.h> header file is used to compute mathematical functions. We are reading ‘radius’ of the sphere. To find the surface area and volume, the following formulas are used.

Surface area = 4 * 3.14 * radius * radius,

Volume = 4/3 * 3.14 * radius * radius * radius.

Runtime Test Cases
 
Output:
$ cc pgm30.c
$ a.out
Enter radius of the sphere :
40
Surface area of sphere is: 19200.000
Volume of sphere is : 256000.000
