Circular motion Questions (2)

Hello guys could you give me answers to these two question so i can check if my answers are right?
Thanks in advance.

1. The drill bit in a drilling machine has a radius of 0.60cm and rotates at 1600 rotations per minute. Calculate:

a) the angular velocity of the bit in rad s^-1
b) the linear velocity of a point on the outer edge of the bit

2. A car is travelling around a circular path of a radius 580m at a constant speed of 45km h^-1. Calculate its angular velocity.

Hi and welcome to TSR physics.

You misunderstand how this forum works.
