I think most of that had been done by the 1500's!
Knowing that there is a constant ratio between radius and circumference
has been known for millennia. Egyptians, Indians, Chinese etc.
The approximation of 3 was used by many (in the bible?)
I think the reeks squeezed a circle between 2 polygons to get a good value.
Presumably that method could be used to get an increasingly accurate value
as the sides of the polygon increase?
