Recursive Calculation of Pi using Archimedes Recursion

Archimedes approximated the value of Pi by inscribing a circle with a regular polygon. First a hexagon and then a 12 sided dodecagon, then 24 sides and so on to 96 sides. His method of computing the perimeter of each successive polygon can be expressed as a recursion. For my class at Seminole State I have assigned this as a homework problem and this video summarizes the solution of the problem.
