How to calculate the volume of a sphere using C programming language?

The volume of sphere is nothing but the capacity of the shape.

Volume of a sphere formula is −

$$V\:=\:\frac{4}{3}\Pi\:r^{3}$$

Algorithm

Step 1: Enter radius of sphere at runtime Step 2: Apply the formula to variable         Volume=(4/3)*3.14*rad*rad*rad Step 3: print the volume Step 4: stop

Program 1

 Live Demo

#include<stdio.h> int main(){    float vol;    int rad;    rad=20;    vol=((4.0f/3.0f) * (3.1415) * rad * rad * rad);    printf("the volume of a sphere is %f
",vol);    return 0; }

Output

the volume of a sphere is 33509.335938

Program 2

Following is an example to find Volume and Surface Area of Sphere −

 Live Demo

#include <stdio.h> #include <math.h> int main(){    float rad;    float area, vol;    printf("Enter radius of the sphere : 
");    scanf("%f", &rad);    area = 4 * (22/7) * rad * rad;    vol = (4.0/3) * (22/7) * rad * rad * rad;    printf("Surface area of sphere is: %.3f", area);    printf("
 Volume of sphere is : %.3f", vol);    return 0; }

Output

Enter radius of the sphere : 4 Surface area of sphere is: 192.000 Volume of sphere is : 256.000
