Question

A boy is moving in a circle of diameter 5 m calculate the distance covered the displacement when he complete 4 revolutions​

Answer 1

Answer:

distance = 62.84 m  displacement = 0

Explanation:

distance of an object is moving in a circular path gonna be equal to the circumference of a circle.

radius = diameter / 2

5/2

distance ( in circular path ) = 2πr

2 X 22/7 X 5/2

110/7

= 15.71 m

now, since the boy is taking 4 revolutions, we gonna multiply 4 to the circumference:-

After 4 revolution distance: 4 x 15.71 m

= 62.84 m

displacement will be 0 (zero) since the initial and final position will be the same.

I HOPE THIS WILL HELP YOU OUT:)
