The pi ratio is strong evidence that a wheel is used somewhere in their surveying tools.

When I was a boy, I asked my mom how the Egyptians made their pyramid foundations straight. Without looking up from her book, she replied "pull a string tight". Then I thought I'd trip her up with how they made the foundation level. Without hesitation she said "dig a trench and fill it with water."

She shoulda been an engineer!

It is as far as I understand only wheeled transportation that was late in Ancient Egypt. They used wheels for pottery before they had wagons.

Most civilizations discovered. No one care about a wheel. The wheel itself is useless. Not everyone discovered the axle though, and even less created roads.

I have responded to a sibling comment with more information or examples. I hate this because I don't care about pyramids or Egypt, but I feel myself compelled to respond, I'm so sorry it's not against you, It's a recent pet peeve.
