Answer:
The process used for finding the path is the same process used to find the arc length of a circle in geometry, we just divide the arc length by the wheel circumference to find wheel rotations.
The pivot turn does twice as many rotations as a point turn because only one wheel is doing the turning.
With the wheel turning 5.50" in one revolution, it would travel: 5.50" x 2.3 revolutions or 12.65" total. Since the circumference is equal to πx D, it is equal to: 3.14 x 3.125" = 9.81". With the wheel turning 9.81" in one revolution, it would travel: 9.81" x 3.625 revolutions or 35.56" total.
