Personally I would stick to LxW spacing and not sweat measuring along the circumference especially since thirteen sprinklers seems like overkill for the roughly 1256 sq ft of area. You could look to 8.6.3.2.5 (2016) for something along the same lines but this section is for measuring max distance from curved walls but the idea is the same: the standard has you measuring straight out and not along the circumference. By my estimation you could probably get by with only 8 sprinklers (with a 20 ft throw), one at each quadrant and in-between quadrants, so I wouldn't lose sleep with thirteen EC sprinklers in this area.
