...unless you're a child or an adult with a small frame. I'm 6'3" and in the low 300s so if I had an appointment in that building I'd say fuck it and go get some fish 'n' chips instead.

Look at my explanation again carefully. The formula for the entire circular door is 2*pi*r, and the radius of the doorway is 100 cm (or 200 cm diameter). So, 2*3.14*100=6.28*100=628 cm.

Each opening is approximately 1/6 of 628 cm; and that in fact is 60 degrees out of a 360 degree circle.
