Hello Jon

A famous value for pi 3.125, 3 1/8th and 25/8 is found in a rather unusual way.

In imperial measure Avoirdupoise Weight 16 drams or 437.5 grains = 1 ounce. Now the number 437.5 I first thought odd until it popped up in the pyramid as the number of feet in the height measured in indus valley feet 13.2 inches.

280 royal cubits = 437.5 indus feet also known as the old Saxon foot 13.2 inches. From my last post there are 25 digits in a royal cubit and so in the height of the pyramid there are 7000 digits.

The base of the pyramid 440 royal cubits x 25 = 11000 digits and immediately the numbers 7 and 22 become apparent as in 22/7 it's right there in front for all to see.

Now comes what is called the Babylonian value for pi 3.125 found at Susa in 1936 I think. The height of the pyramid 280 x 3 1/8th = 875 royal cubits and this is twice 437.5 or the same number as indus feet in the height.

Looking at the base of the pyramid 440 x 3 1/8th = 1375 royal cubits or the same number as indus feet in the base 687.5 indus feet.

The same number 68.75 imperial feet = 2 x KC length 412.5 inches same number again.

The other 2 values are pi itself to first 10 digits and another 3.142561983 which it concerns the old problem of 'squaring the circle'
