A bicycle tire rotates at 30 radians/s. If the bicyclist travels at 10m/s, what is the diameter of the tire?

30Rad/s * 1Rev/6.28Rad * 1s/10m = 0.478
Rev/m = 2.093 m/Rev = Circumference(C).
pi*D = 2.093
3.14*D = 2.093
D = 0.67 m = Diameter.
Rev/m = 2.093 m/Rev = Circumference(C).
pi*D = 2.093
3.14*D = 2.093
D = 0.67 m = Diameter.
