The Eyptian Pi value is actually a value for area as you suggest and I have suggested the same it does not give a circumference value.
The value 9.87654321 is also a value for area and the square root is 3.14269680 so not only a value for a square but also very close to real Pi. Closer than 22/7.
The fact is if 22/7 is multiplied by 9800/9801 then the result is 3.142536476 even closer to real Pi and as a fraction is 2800/891. this reverses the bases being base 7 over base 22.
3.142857143 + 3.142536476 = 6.285393619 / 2 = 3.14269680 and this is the square root of 9.87654321.
This is a fact. Jacob obviously knows that the AE only did the things he suggests but it is not unreasonable to assume this could have been hidden knowledge. Because they did not record pi as such does not mean they were not aware of it, more likely as 2pi. 44/7.
3.125 x 256/81 = 9.87654321 this is a measure of area as is 256/81. This is all I am pointing out, not making the assumption that the AE scribes who published to the population knew Pi or Pi approximate, surely the design of G1 tells us this. I don't want to argue about it because these numbers just are and I agree to never seeing your approach in any book, only seen it recently on this website and pointed it out. Babylonian Pi ( which is not Pi at all, no where near it) comes out of this arrangement for the calculation of area using 8/9 of the diameter. The question to ask is could it be of Babylonian origin? I have no idea.
