## History

Since Antiquity, scholars have known that the perimeter of a circle is in a constant ratio to
its diameter. While the Babylonians admitted that this ratio is 3, the Egyptians identified it as .
Archimedes was the first mathematician to calculate an approximate value of the
number , from regular polygons of

*n*sides inscribed and circumscribed in a circle. In this worksheet, I reproduced several diagrams, so we can figure out the approximation.
