Thanks MJ:
you can also add... 1318 ( total horizontal length) divided by 200/pi = 20.7...a Royal cubit.
IOW a circle having a circumference of 200 Rc will have a diameter of 63.67 Rc...= 1312".
Measure the ceiling section and you have the answer.
Pi is used extensively in the sub section of the structure, but how accurate does it have to be for others to realize the designer's intent 2...3...4...5 decimal places? It's impossible to accomplished from the measures provided.

But...as you have pointed out, the southern section of passage is 31.4 Rc in length...this is more accurate than the northern section as calculated above...therefore there must be a reason why?

Best.
