The Rhind Mathematical was written hundreds of years after the construction of the Great Pyramid. My 8/9 model indicates that the ancient Egyptians knew how to square the circle in a crude way in the Pyramid Age which only shifts back the history of geometry a few hundred years.

But to answer your question its only important to those who debate the development of human cognition across the world, and to those Egyptologists with a broad perspective. Professor Miroslav Verner has question whether or not Archimedes learnt geometry during his stay in Egypt.

My sociological perspective is that mathematics developed in every civilisation of the world irrespective of race. Egypt was one of the first great civlisations so it is to be expected that mathematics was a corner stone of advancement. I think it was Pliny who wrote 'always something new out of Africa'.

It seems very likely that geometrical ideas were first understood in Egypt. The formula for the volume of a truncated pyramid in the Moscow Mathematical Papyrus may also have been known as far back as the Pyramid Age. Could you have figured out such an ingenious formula?

Africans the world over should be proud to think that the most famous geometric discovery of Archimedes was actually discovered in Egypt 2,000 years earlier, which I believe is the case.

Darwin had to concede that many of his ideas had actually been published in an obscure journal which he had not read, but I think the author was an insignificant farmer who had an article published in an agricultural journal. I think it likely that someone else will, at some time in the future, promote my key ideas without having read my work. Only an academic of some standing has the potential to change the way all the world thinks on academic matters.
