Uniform Circular Motion?

Okay, sorry guys but I need a little help...

a bicycle is moving at 9.0 m/s. what is the angular speed of its tires if their radius is 35 cm? how do I find the solution?

The circumference of the tire is pi times 2 times 35 cm.

Pi times 2 times 35 cm of road goes by every rotation to the wheel.

so 9 m/s divided by (pi * 2 *0.35) M will be ..... the angular velocity in rotations per second.

linear velocity=angular speed * radius

9.0 m/s = W * 0.035 m

W=257.14 radians/second
