Distance: #30pi# meters

Displacement: zero meters

Explanation:

-The distance is #2pir# (or #pid# "the circumference") times the number of rounds travelled.

#d# is the diameter which is #15m#, so the distance is the number of rounds (#2#) times the diameter times #pi#

#d=2(15)pi=30pim#

-The displacement is zero meters since the particle has returned to the same point as the original point.
