The difference between 185 inches(10x18.5) and 176.662 inches is 8.338 inches. This is two of my hand breadths!(8.338÷2=4.169) Remember, you must take into account two hand breadths, one for the opposite sides of the circular object. | The difference between 185 inches(10x18.5) and 176.662 inches is 8.338 inches.
