Hakan,

Drop the parentheses after .PI and you'll be good to go. When I enter your code in, the error I receive says "There was an error with your code: TypeError: '3.141592653589793' is not a function (evaluating 'Math.PI()')".

You want simply:

var circumference = Math.PI * diameter;

Hope this helps!

Erik
