I accept that I did that and apologise for it but I understand where you are coming from now.
This method of subtracting 1/9 th of the diameter from the diameter and then squaring is what I should have noticed and I accept that this does demonstrate a completely novel way of working out area in an easy and equitable way and using 22/7 gives a different result and is not what is being used.
What is being used is 256/81 the rhind 50 solution I think but wonder if you agree this?
1/9 is 0.1111r so you can probably see why I have been converted.
If this is how they worked out area how did they do circumferences?
What is really intriguing me is that 256/81 x 800/256 = 9.87654321 and 800/256 is 3.125 so is there any evidence 3.125 was used by the Egyptians?
take 1/9 of 11.1111111111 off it and see what you get.
