  1. TamTroll Pi is a property of circles and the like. It is necessary for finding the radius from the area, or the reverse, and some other things. Thing is, in any formula it shows up in, if you find all the numbers, then treat Pi as a variable and solve for it, and write out the number... You'll never stop, because the decimal places just keep coming. I believe the pattern of digits also doesn't repeat, which is why memorising it to however many decimal places is a big deal.
