Just real quick wanted to make a post about surface areas when it comes to hallways!
Here we have a standard hallway (4 foot by 8 foot) and next to it a circular hallway (note: the bottom flat surface is 4 foot wide and from the edges of that flat surface straight up is 8 foot to the arc, very top of the ceiling is a little higher than 8 foot)
Assuming the lengths of each hallway are the same , lets say 5 feet, the total surface area for the standard hallway is:
8ft x 5ft = 40sq ft ( x 2 for the other wall) = 80sq ft
4ft x 5ft = 20sq ft
equaling 100sq ft
For the round hallway:
287.4272 inches / 12 = 23.9523ft
23.9523ft x 5ft = 119.7613sq ft
Extra surface area just under 20%
