Question

A body is moving along circular path of radius 7 m while it reaches diametrically opposite end in its first rotation,distance and displacement covered by it is

Answer 1

Answer:

distance=πr²

              =22/7×7×7

              =154 m

displacement=2×r or d

                      14 m

                     

Answer 2

Answer:

14m

Explanation:

According to your question, the body moves from point A to point B thereby completing half a revolution. 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
