Java program to calculate area of circle rectangle and triangle using switch statement

// Java program to calculate area of circle rectangle and triangle using switch statement
import java.util.Scanner;
public class FindAreaUsingSwitchStatement 
{
   public static void main(String[] args) 
   {
      Scanner sc = new Scanner(System.in);
      System.out.println("MENU:");
      System.out.println("1.Area of circle");
      System.out.println("2.Area of triangle");
      System.out.println("3.Area of rectangle");
      System.out.println("Please enter any of the above option: ");
      int num = sc.nextInt();
      switch(num)
      {
         case 1: System.out.println("Please enter radius of circle: ");
         double radius = sc.nextFloat();
         double areaCircle = (22 * radius * radius) / 7;
         System.out.println("Area of circle is: " + areaCircle);
         break;
         case 2: System.out.println("Please enter base and height of triangle: ");
         double base = sc.nextFloat();
         double height = sc.nextFloat();
         double areaTriangle = (base* height) / 2;
         System.out.println("Area of triangle is: " + areaTriangle);
         break;
         case 3: System.out.println("Please enter length and breadth of rectangle: ");
         int length = sc.nextInt();
         int breadth = sc.nextInt();
         int areaRectangle = length * breadth;
