c/d=x2.6/x=2.6/1=2.6=pi (π) Pi is defined as circumference over diameter, or the area around a circle divided by (in this case) its width. For this project, as the circle's width isn't very important, we will represent it with x. The circumference, which is the border, is 2 diameters and a bit, which I have calculated to be .6060 repeating, which I have simplified to 2.6, so the circumference is 2.6*x, or 2.6x. 2.6/1 is 2.6, so Pi is 2.6 (Actually this is lying with visual proofs, and a very bad one at that, I'll make an explanation soon.) I hope this becomes my chicken
