2.2 (Compute the volume of a cylinder) Write a program that reads in the radius and length of a cylinder and computes the area and volume using the following formulas:

area = radius * radius * p volume = area * length Here is a sample run:

Solution:

import java.util.Scanner; public class Exercise02_02 { public static void main(String[] args) { Scanner input = new Scanner(System.in); // Enter radius of the cylinder System.out.print("Enter the radius and length of a cylinder: "); double radius = input.nextDouble(); double length = input.nextDouble(); double area = radius * radius * 3.14159; double volume = area * length; System.out.println("The area is " + area); System.out.println("The volume of the cylinder is " + volume); } }
