Exercise Bug

The first exercise asks to declare a variable named "circumference" and then store the Math.PI() inside of it, when I do that, it says I haven't declared the variable, I've tried everything, is not working, help.

I noted you referenced Math.PI(), it's important to remember Math.PI is a constant not a function.

I just realized a problem here, you haven't gotten to the function section in the course. And I don't think the course touched on constants. So that's a problem.

Hello,

It's been a long time and I had to look at it for a little bit until I realized what it was asking for. What were you using that made it not pass? In the challenge, the variable must have a value in it after getting declared for the challenge to even realize that you declared it (it doesn't see the variable if you just declare it). Remember that the circumference is the diameter multiplied by PI. Make sure you use the diameter variable that is already defined as well as the Math object PI. You can get the value of PI from the Math object by calling it like so: Math.PI

Once you put it all together (either on it's own declaration or as part of the variables that are already being declared) the challenge will pass. Hope this helps you.

Cheers!
