 * Specification **

Write a program which will calculate the circumference of a circle:
 * ask the user to enter the radius of the circle
 * ask the user the unit of measure (mm, cm, m or km)
 * calculate the circumference of the circle using the formula C = 2 𝛑 r

__**Code**__


 * Variables **

Create 3 variables:


 * //radius//: radius of circle (entered by user)
 * //units//: unit of measure for radius (entered by user)
 * //circumference//: calculated circumference of circle

Make sure each variable is unticked so it doesn't get displayed at the top of the screen.




 * Script **




 * Testing **

Test your program works with 3 different radii
