What is the angular speel of a 19-in. diameter bicycle wheel if the bicycle if traveling at 29 ft/s?

• trigonometry -

Speed = R w
R = 9.5 inch
Speed = 29*12 = 348 inch/s
w = angular speed = 348/9.5 = ? radians/s

Speed and R must both use the same length units when calculating w. I chose to use inches
