Two gears are connected and are rotating simultaneously. the smaller gear has a radius of 2 inches, and the larger gear has a radius of 8 inches.

two circles touching at one point. larger circle has radius of 8 inches. smaller circle has radius of 2 inches.

part 1: what is the angle measure, in degrees and rounded to the nearest tenth, through which the larger gear has rotated when the smaller gear has made one complete rotation?

part 2: how many rotations will the smaller gear make during one complete rotation of the larger gear?
