java program very important programs

 Write a program that reads in the radius

and length of a cylinder and computes the area and volume

Description:

using the following

formulas:

area = radius * radius * p

volume = area * length

Solution

 import java.util.*;

public class Message {

 public static void main(String[] args) {

    Scanner in = new Scanner(System.in);

   float radius,area,lenght,pi=3.14f;

   System.out.println("Enter the radius");

   radius=in.nextFloat();

   System.out.println("Enter the lenght");

   lenght=in.nextFloat();

   area=pi*radius*radius;

   System.out.println("The area of clyinder = "+area);

   System.out.println("The volume of clyinder ="+(area*lenght));

 }

}

Output
