distance would be = 9 π
displacement would = π
pokhriyalsam786:
speed is 3π per sec. for 3 sec. so s= ut , s = 3π×3 = 9π (distance)
2π stamds for 360°
after every 2π , body returns to
starting point. making displacement zero
so net displacement till 8π (4×2π) is 0
so net displacement is due to 9th π
so displacement would be just π
dispace would be equal to diameter too
so it also can be 2R
12 metres

Explanation:
Distance=speed×time
=3pi/second × 3 seconds
=9pi
distance =9pi
As it is a circle,displacement is always r(radius).
So, displacement is 6m
I have explained it!
