(a) well, there are 2pi radians or 360 degrees per revolution.
(b) the circumference of the wheel is 2pi*2.08 inches. That's how far it moves on each revolution.
A skateboard wheel has a radius of 2.08 inches and is turning at a rate of 945 rpm.
a. what is the angular speed in radians per second? in degrees per second?
b. how fast is the skateboard traveling (in miles per hour)?
