Finding PiDate: 2/8/96 at 10:34:32 From: Anonymous Subject: geometry Why is pi 3.14? Date: 3/26/96 at 21:13:34 From: Doctor Jodi Subject: Re: geometry Actually, pi isn't 3.14. :) Pi is a really cool number, because (as far as we know) it NEVER ENDS and its digits NEVER REPEAT in any pattern. Mathematicians have used computers to calculate 2 BILLION decimal places, and pi (not unlike the energizer bunny) keeps going, and going, and... But without a pattern. Where did pi come from? Well, the Greeks asked a great question (they were wonderful at posing questions, and solved a lot of them, too): Find a square equal in area to some circle. To see their dilemma, trace a circle onto a piece of graph paper. Can you count the number of squares within the circle? How else might you try to determine the area of the circle? (Hint: one thing to try is to find a method for determining the area of a polygon, like a pentagon or octagon, and see if you can apply the same method to the circle.) -Doctor Jodi, The Math Forum |
