Find the angular size of a circular object with a 33​-inch diameter viewed from a distance of 44 yards.

OpenStudy (mathmate):

A diagram always helps. |dw:1473510965895:dw| angular size = 33"/40 yds radians But we need to change the measurements to the same units, so angular size = 33" / (40 yds * 3 ft/yd * 12"/ft) radians =33/(40*3*12) radians
