The Math Object....

"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."

This is question which doesn't let me pass.....wanted help.... I wrote the answer : var circumference = Math.PI(5.75, 3.14159); & I tried to apply .. Math.PI(diameter); But still it didn't recognize the var....... What should I try then.....?

I just figured it out myself if you still need help.

So after you name the var use diameter as an argument then multiple it by Pi, ie...

var circumference = (diameter) * Math.PI;

Math.PI is a property, not a method. You cannot pass a variable into it--it is a variable. Instead, multiply it by your diameter.

Alex if you still in trouble yet. Use this code var circumference = Math.PI * ( diameter);

var circumference = Math.PI*diameter;

Make sure to check all the spelling.

I can't believe how easy it was once I figured it out lol, I was putting it above the var diameter. Hope this helps someone else. var diameter = 5.75, circumference = diameter * Math.PI a = 17, b = 42, c = 1337, ageIfILiveToYear2100 = (new Date(2100, 0, 1) - new Date(1995, 5, 16, 7, 20)) / (1000 * 60 * 60 * 24 * 365.242);
