Question

A boy running on the circular path of radius 35 cm completes half circle . Find distance and displacement.

Answer 1

Answer:

As the boy has completed half the circle(semicircle), it means that the distance travelled by the boy is of πr. Therefore, the distance travelled by the boy is 110 m. Displacement is the shortest distance travelled by an object or the path travelled by an object in a particular direction. → The displacement is 75 m

Explanation:

i hope its help to you ✌

Answer 2

distance is 2πr = 2×π× 35=229.9

displacement= 2r= 2×35= 70
