You can derive it from Euclid's geometric axioms. (Archimedes calculated pi by inscribing circles with regular polygons).
EDIT: I think it was Archimedes not Aristotle
Modern day it is defined from
smallest positive x such that
cos(x) = 0
then x = pi/2
(angles in radians, cos defined in terms of Taylor series).
