Question

a body is moving along a circular path of diameter 280m. what will be the distance and displacement of the body when it completes half revolution?​

Answer 1

Answer:

$distance = \pi \: r \\ 3.14 \times 140 \\ 439.6m \\ displacement \: = shortest \: distance \: between \: initial \: and \: final \: position \\ 2r = 140 \times 2 = 280m$
