Suppose you are riding a stationary exercise bicycle, and the electronic meter indicates that the wheel is rotating at 8.6 rad/s. The wheel has a radius of 0.30 m. If you ride the bike for 2070 s, how far would you have gone if the bike could move?
2070s*8.6/(2 pi) = number of wheel revolutions.
Multiply that number by 2 pi R for the distance you would have travelled.
The answer will be (2070s)*(8.6 rad/s)*R
R is the wheel radius
