The circumference of a circle is given by circle ircum$=2\mathrm{.}0****$ circleRadius. Declare double variables circleRadius and circleCircum. Then, read circleRadius from input and compute circleCircum using the formula.

Ex: If the input is $3\mathrm{.}80,$ then the output is:

$23\mathrm{.}88$

Note: Use the constant Math.PI for $.$

import java.util.Scanner;

public class Circle $\{$

circleCircum $=2\mathrm{.}0**$ Math.PI $*$ circleRadius;

$\}$

System.out.printf$("\%\mathrm{.}2$f
