The angular speed of a large pulley wheel that has a radius of 15, is 50 revolutions/min. Find the angular speed and the rim speed of the smaller wheel that has a radius of 5.

The rim speed is going to be the same.

I got the angular speed but I can't figure out why the rim speed is 4700 cm/min.

Please Help
