17.3333r is a radius so diameter is 34.666r x 1632/520 = 108.8 miles this is a Thom unit and will factor using 33/34 to give 105.6 units divide by 72 to get 1.4666r units
31680 is the side of a square the arc being 31680/9x10 = 35200 100 Lunar eclipse years (352/24 = 14.666r
7000 as a radius x2 = 14000 x 22/7 = 44000 feet/3 = 14666.666r
