Program to calculate Volume, Curved Surface Area and Total Surface Area of Cone in Java

package com.hubberspot.mensuration.example;

import java.util.Scanner;


public class Cone {
   public static void main(String[] args) {
      Scanner input = new Scanner(System.in);

      double radius = 0;
      double height = 0;
        
      double slantHeight = 0;
      double volume = 0;
      double curvedSurfaceArea = 0;
      double totalSurfaceArea = 0;

      System.out.print("Enter the radius of base of Cone : "); 
      radius = input.nextDouble();

      System.out.print("Enter the height of Cone : "); 
      height = input.nextDouble();

      volume = (Math.PI * radius * radius * height) / 3;
  
      slantHeight = Math.sqrt(height * height + radius * radius);
  
      curvedSurfaceArea = (Math.PI * radius * slantHeight);
  
      totalSurfaceArea = Math.PI * radius * (radius + slantHeight);

      System.out.println("");
      System.out.println("The Slant height of Cone is : " + slantHeight);
      System.out.println("The Volume of Cone is : " + volume);
      System.out.println("The Curved Surface Area of Cone is : "
   + curvedSurfaceArea);
      System.out.println("The Total Surface Area of Cone is : "
   + totalSurfaceArea);


  }

}
