To get linear velocity isnt the radius multiplied by the angular velocity in order to get linear velocity? Im lost I keep getting the wrong answers. For angular velocity I got 1,803,600 radians/hour and for linear velocity I got 23,741, 676 miles/hour. I dont get it.

The problem is: The radius is 21.910 inches. A wheel rotates 150.5 times per second. I need to find:

1. The angular velocity in radians/hour.

2. The linear velocity in miles/hour.
