How big is the octagon?

Question

looks like the kotc is smaller?

what about the pride ring?

Answer 1

The cage is an eight-sided structure with walls of metal chain-link fence coated with black vinyl and a diameter of 32 ft (9.75 m), allowing 30 ft (9 m) of space from point to point. The fence is 5'6" to 5'8"  high. The cage sits atop a platform, raising it 4 ft (1.2 m) from the ground. It has foam padding around the top of the fence and between each of the eight sections. It also has two entry-exit gates opposite each other.

Idk about the pride ring.
