Help!!

I don't know why but I put the exact code into wwebschools and it worked (i replaced diameter with 5.75 in webschools). It says to find the circumference and put it into var circumference so wouldn't you think that the code will work?, Thank you

var diameter = 5.75,
          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);
      var circumference = (Math.Pi * diameter);

You'll just need to capitalize both P and I in Pi for this to work. Math.Pi is undefined, but Math.PI will give you a value of 3.141...
