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
#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\n",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 −
#include <stdio.h> #include <math.h> int main(){ float rad; float area, vol; printf("Enter radius of the sphere : \n"); 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("\n 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
