Write code which takes a double input from the user and creates a circle with that radius. The code should calculate the area of the circle, then double the radius of the circle and print the new area of the circle. Sample run: Enter radius: > 2.0 Area: 12.566370614359172 Radius is being doubled... Area: 50.26548245743669

import java.util.Scanner;

import (*software used for shapes*);

public class (*enter class name*){

 public static void main(String[] args){

   Scanner scan = new Scanner(System.in);

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

   double r = scan.nextDouble();  

   Circle c = new Circle(r);

   double area = c.getArea();  

   System.out.println("Area: "+area);

   System.out.println("Radius is being doubled...");  

   r = c.getRadius();  

   c.setRadius(r*2);

   area = c.getArea();

   System.out.println("Area: "+area);

Explanation:

I know this is late, but I am putting this here for future people trying to solve this problem.

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
