Question

A body is moving along a circular path of radius 140 m. What will be the distance and displacement of the body when it completes half revolution?​

so distance is 439.82 meter

Displacment is distance between initial and final position

here it is the diameter of the circle

so

DISPLACMENT is 280 meter

Answer 2

440m is the distance.
