YouTube number boffin calculates Pi using...pies

A YouTube video blogger has quite accurately calculated the value of pi using nothing but chalk, a calculator and a LOT of pies.


Boffin blogger Numberphile used pies to calculate pi to be 3.13834 - pretty close to pi's actual value of 3.14159(...). Is this how Archimedes calculated pi?
