I assume it has something to do with figuring out the radius of each circle? Not sure how to get there though.
It's deduction. Because the formula exists it must exist for all diameters of room and central column. Therefore you could have a circular room with a 0 diameter column, at which point the chord length is the diameter of a circular carpet,
