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.
