Question

write a program in java to calculate volume of a sphere whose radius is 7.5 cm.​

Answer 1

Program:

import java.io.*;

public class Main{

     public static void main(String args[]){

           System.out.println("Volume of sphere when radius is 7.5cm is : "+((4/3) x 3.14 x 7.5 x 7.5 x 7.5)+"cm.");

     }

}

Output:

Volume of sphere when radius is 7.5cm is : 1324.6875cm.

Explanation:

1. volume of sphere 4/3 πr³
2. so i calculated (4/3) x 3.14 x 7.5 x 7.5 x 7.5
3. and printed the value directly
4. so it make less lines
5. and it will allocates less space when compared to initializing variables and passing values to them
