Page "Great Pyramid of Giza" Paragraph 5
Verner wrote, " We can conclude that although the ancient Egyptians could not precisely define the value of π, in practice they used it ".
Petrie, author of Pyramids and Temples of Gizeh concluded: " but these relations of areas and of circular ratio are so systematic that we should grant that they were in the builder's design ".
Others have argued that the Ancient Egyptians had no concept of pi and would not have thought to encode it in their monuments.
They believe that the observed pyramid slope may be based on a simple seked slope choice alone, with no regard to the overall size and proportions of the finished building.
