Question

After having done the hand calculation and pseudocode for a program that models inflating a spherical balloon, now implement the task in Java. Remember, first the balloon is inflated to have a certain diameter (which is provided as an input). Then you inflate the balloon so that the diameter grows by an inch, and display the amount the volume has grown. Repeat that step: grow the diameter by another inch and show the growth of the volume.

Complete the following program.

 

 

 

import java.util.Scanner;

public class Balloon
{
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
System.out.print("Diameter: ");
double diameter = in.nextDouble();

int volume1 = (pi*diameter*diameter*diameter/6);

System.out.printf("Increase: %.0f",diameter);
System.out.println();

int volume2 =(pi*diameter*diameter*diameter/6);

System.out.printf("Increase: %.0f",diameter);
System.out.println();

int growth = (volume2 - volume1);

int volume3 =(pi*diameter*diameter*diameter/6);

}
}
