Create a variable named "circumference" and assign the correct value to it by using the "diameter" variable and Math.PI.

Hi,

I think i may have found a potential bug on the challenge.

I have declared the circumference variable with the following code:

var circumference = Math.PI() * diameter;

Yet I still get the following error:Bummer! No variable named "circumference" has been defined. Make sure to declare the variable like: var circumference =...

Any help would be much appreciated.

Cheers, Fraser

No, there is not bug. The problem is that you're trying to call a function called Math.PI() when in fact Math.PI is a constant. So you would just remove the parentheses and then I bet it'll work out.
