<1. We know 24883.2 = 69.12 x 360 and the diameter = 7920 using 3.1418181818
2. The old Egyptian value for pi 3.160493827 can be used with your number 7875 = 24,888.88888
Working back using 24,888.88888 / 360 = 69.13580247 / 60 = 1.52263374 miles = 5996083.9506 feet / 8 = 760.4938 feet the socket side of pyramid 9125.925 inches (Petrie 9125.9 inches).
There is a lot more to this and perhaps if you could work your rads again we may find it.>
Yes, thanks for bringing back my memories of previous discussions pertaining to Earth dimensions and the GP. LOL! OK, here's another curve ball tossed over 10 yrs. ago pertaining to that Earth Circ. value 24,888.888 / 8 = 311.111 x old ratio sq.rt.2 99/70 = 440 as in base GP cubits. This being also the value of the half diagonal base in cubits. Or 481.25 Ft. height / .9 = 534.7222 Ft., when using cubits of 20 5/8th. ins. There are probably dozens of different Earth Circ./Rad. values in that pile of limestone blocks, LOL!
