First off all, I am so new to this and just googled and tried to learn what to do and I came up with this and it seems it work. public class Codegym { public static void main(String[] args) { printCircleCircumference(5); } public static void printCircleCircumference(int radius) { //write your code here double result = 2*3.14*radius; double roundOff = (double) Math.round(result * 10) / 10; System.out.println(roundOff); } } // 31.4

Hi there! Just for reference: when you want to input code snippet in your answer, please use the code button ( in the middle of the type box, after link, add picture -> next): it's really more readable for other viewers :) Thank you!

hava a look at String.format or System.out.printf, e.g.:

System.out.printf("%.2f", 5.54646);
