Question

OOLSVIEW 215710514 (ratected View) Wo CTED VIEW Beca 1. Write a program that reads in the radius and length of a cylinder and computes the area and volume using the following formulas area pi radius volume area length your program should have length as integer variable radius as double variable pi as Named Constant It prints the output with maximum 2 decimal digits. If area is greater than 20, it checks if the area is odd or not and prints it Here is a sample nun: Enter the radius and length of a cylinder: 5.5 12 The area is 95.0331 The volume is 1140.4 OAsk me aything

Answer 1

Program1.java

import java.util.Scanner;

public class Program1 {
  
   public static void main(String args[]){
       Scanner sc = new Scanner(System.in);
      
       int length;
       double radius;
      
       System.out.print("Enter the radius and length of a cylinder: ");
       radius = sc.nextDouble();
       length = sc.nextInt();
      
       double area = Math.PI * radius * radius;
       System.out.println("The area is "+area);
       double volume = area * length;
       System.out.println("The Volume is "+volume);
   }
