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

shutvik [7]

R - radius of the larger circle
r - radius of the smaller circle

Circumference of the larger circle = $2R\pi=2\times 8\pi=16\pi$
Circumference of the smaller circle = $2r\pi=2\times 2\pi=4\pi$

Part 2: During one complete rotation of the larger gear both gears pass the same distance $16\pi$ .
Therefore, the smaller gear makes $\frac{16\pi}{4\pi}=4$ complete rotations.

Part 1: During one complete rotation of the smaller gear both gears pass the same distance $4\pi$ .
Therefore, the larger gear makes $\frac{4\pi}{16\pi}=\frac{1}{4}$ of a complete rotation.
Since one complete rotation corresponds to 360 degrees, 1/4 of a complete rotation corresponds to 360/4=90 degrees.
