C :

#include <stdio.h>
int main()
{
	int r;
	scanf("%d",&r);
	#define pi 3.14159
	printf("VOLUME = %.3f",(4/3.0)*pi*r*r*r);
	return 0;
 } 

C++ :

#include<stdio.h>
#include<math.h>
#define PI 3.14159
int main()
{
	int R;
	double X;
	scanf("%d",&R);
	X=(4/3.0)*PI*pow(R,3);
	printf("VOLUME = %.3f",X);
	return 0;
}

Java :

import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int R = scanner.nextInt();
        double pi=3.14159;
        if (R>=1 && R <=2000 ) {
            double V =(4 / 3.0)* pi *R*R*R;
            System.out.println("VOLUME = "+String.format("%.3f",V));
        }
    }
