Answer:
Distance wil be 660m and displacement should 0cm
Explanation:
radius of circle=21cm and circumference = one round of the circular path=2×pie×r and there are 5 round then 2×pie×r×5=660m
displacement should be 0cm because the starting point and the ending point are same i am shortest distance from starting point to ending point.
like my answer if anybody understand

Answer:
The distance moved is equal to two circumferences:
d = 2 × 2 π r = 264 m
The magnitude of displacement is the distance in a straight line between the start position and end position. Since 2 complete revolutions have been made the start and end position are the same position. That makes the displacement zero.
