The volume of a hemisphere is given by

$.$ Declare double variables hemisRadius and hemisVol. Then, read hemisRadius from input and compute hemisVol using the formula.

Ex: If the input is $3\mathrm{.}30,$ then the output is:

$75\mathrm{.}27$

Note:

Use the constant Math.PI for

$.$

can be computed using $*.$ import java.util.Scanner;

public class Hemisphere $\{$

public static void main$($String$[]$ args$)\{$

Scanner scnr $=$ new Scanner$($System$.$in$)$;

$/*$ Your code goes here $*/$

System.out.printf$("\%\mathrm{.}2$f
