Question

a particular is travelling in a circle of diameter 15m calculate the distance covered and displacement when it completes 2rounds

Answer 1

s=2 round
d=15cm
w=?
w=s*d
w=15*2
w=30cm is the displacement of 2 round

Answer 2

Given, diameter = 15m

Therefore, circumference
= π×diameter
=(22/7)*15 metres

Therefore distance covered in 2 rounds
=2 * circumference
=(660/7) m
= approx. 94.3 metres

Displacement=0 metre [since the particle returns to origin]

Hope it helps. Kindly mark as brainliest if you are satisfied with the answer. Thanks!
