Thanks Harte! I just learned something. Appreciate the response. Interesting this 22/7 ratio. Any idea why they used it? Was it arbitrary.
Yes, it was arbitrary, sort of. That is, it's obvious that just any random slope won't work. A pyramid will collapse for large slopes, and for
small slopes it loses its granduer (and takes up quite a large area at the base.)
But within a certain range, it was arbitrary. For example, next door at Khafre's pyramid - when dimensions are manipulated in the same way - comes
to exactly 21/7, or 3. This value is 3.0 with three or four zeros after the decimal before digits begin to creep in. That is a testament to the
accuracy for Kahfre's pyramid as well.

Was it the maximum angle of repose they could build the pyramids without structural compromises? Also, since this ratio is pretty close to Pi.
Wouldn't the pyramid come pretty close to describing the circumference of the earth as a coincidence.
Any circle is similar (using the geometrical term correctly) to the Earth's circumference. Pi appears in every circle. Not exactly
Earth-shattering, IOW.
It's been quite some time since I looked into this, but if I remember correctly, a few examples of pyramids exist with a greater slope than
Khufu's.
