Answer:

Below in bold.

Step-by-step explanation:

Part A.

There are  18 sectors in the circle  so each arc  goes through  360/18 = 20 degrees.

The passenger passes through 4 arcs so that is 80 degrees.

The distance travelled from M to J =  (80/360) * the circumference.

The circumference = 2πr = 2 * 200 * π

= 400π feet.

So the distance = (80 * 400π) / 360

= 279.25 feet.

Part B.

The distance for 2 revolutions = 2 * 2 * π  * 200

= 800 π

= 2513 feet.
