Question

The volume of a sphere is calculated by using formula: 

v = `4/3 ∗ 22/7 ∗ r^3`

Write a program to calculate the radius of a sphere by taking its volume as an input. 

Hint: radius = `root3 ("volume" ∗ 3/4 ∗ 7/22)`

Answer 1

import java.util.*; 
public class Q4
{public static void main(String args[])
{Scanner in = new Scanner(System.in);
double vol, r; 
System.out. println("Enter the volume of the sphere"); 
vol = in.nextDouble(); 
r = Math.cbrt(vol * 3 / 4 * 7 / 22);
System. out. println("Radius = " + r); 
}}
