Answer 1

Explanation:

Since distance is the length of path covered therefore it will be equal to half the circumference

i.e. 1/2 × 2pi r or pi × r.

And the displacement is equal to the distance between initial and final point.

Therefore it will be equal to the diameter or r+r=2r.

Answer 2

Answer:

distance covered in half revolution = circumference of a semicircle= πr

and the displacement=diameter of circle =2r.

so, distance = πr and displacement=2r
