help me please

public class Solution { public static void main(String[] args) { printCircleCircumference(5); } public static void printCircleCircumference(int radius) { //write your code here double pi = 3.14; int r = radius; double c = 2 * pi * r; System.out.println(c); } }

public static void printCircleCircumference(int radius) { //write your code here double pi = 3.14; double circumference = 2 * pi * (double) radius; System.out.println(circumference); }

may this will help you - public class Solution { public static void main(String[] args) { printCircleCircumference(5); } public static void printCircleCircumference(int radius) { double circumference = (Double) (2 * 3.14) * radius; System.out.println(circumference); } }

i didn't get.

public class Solution { public static void main(String[] args) { printCircleCircumference(5); //Double pi = 3.14; //Double C; //C = 2*3.14*radius } public static void printCircleCircumference(int radius) { //write your code here System.out.println(2 * 3.14 * radius); } }
