Suppose you have a circle with a diameter of 1. If you draw a square with all four sides touching the circle, the perimeter of the square is 4. Now suppose you indent each corner of the square so that they all touch the circle-this will make a cross shape, and the perimeter of it is still 4. Now suppose you indent each corner of the cross so that they again all touch the circle. You can see now that the square is becoming more like a circle, and yet the pereimeter is still 4. This can be done to infinity, therefore, pi equals 4!
