pls. answer

Angular velocity = angular displacement/time.

Consider a particle moving in a circle of radius R.

For a very small change in position, the arc lenth will the the displacement of the particle and the angle subtended will be the angular displacement.

linear displacement = (angular displacement)(radius)

Dividing both sides by time.

linear displacement/time = (radius)(angular displacement)/time

linear velocity = radius x angular velocity.
