8,227 PointsProblem with Math.pi
Create a variable named "circumference" and assign the correct value to it by using the "diameter" variable and Math.PI. See the comment in the script for more information.
I wrote;
var circumference = diameter * Math.Pi;
It says; "Bummer! Sorry! That's not correct. Remember, the circumference should be equal to the diameter times Pi."
Whats wrong in my code?

Traditional math formula looks like this: circumference = (pi)(diameter) ....just use the two variables and Math.PI instead.
var circumference = Math.PI * diameter;

8,227 PointsThanks a lot for pointing it out. I forget to capitalize the Pi. I am new at it and it will take a while getting used to the markdown.

Not sure if quotations were added as part of your answer. Try editing your question and use the Markdown Cheatsheet so those who read your question will be able to see your mistake(s).
