Answer:
To find the distance covered by particle, we find circumference of the circle and divide it by 4(as it travels 1/4 of it)
Circumference = 2× pi × radius
= 2 × 22/7 ×6
12× 22/7
=37.71 (approx)

Answer :
◈ Particle covers 1/4 part of a circle of radius 6m
We have to find pathlength covered by particle.
_________________________________
What is pathlength!
Pathlength is defined as the actual length of path which is covered by moving object.
It is a scalar quantity having only magnitude.
SI unit : m
➝ pathlength = 1/4(perimeter of circle)
➝ pathlength = 1/4 × 2πR
➝ pathlength = π(6)/2
➝ pathlength = 3π
