'Squaring the circle' works with Khufu the Great pyramid of Egypt, but not quite with the two smaller structures..........did they get lazy..?
Khufu's height is exactly the radius of the circle when 'Squared' - piece of luck or very well planned..??
Khufu Pyramid Base length = 230.25 metres *
Khufu Pyramid Circumference (Length x 4) = 921.00 *
Khufu Pyramid Height (=Radius) = 146.58 metres *
* measurements vary dependant on source
