Given a circular wheel that is rotating at the rate of $25$ revolutions per minute. If the radius of the wheel is $50 \space cm$, what could be the distance covered by a point on the rim in one second (Given that $\pi = 3.1416$)

Any takes? Thanks.

    Just use conversion factors. One revolution is $2\pi\times50\text{ cm}$ (why?), and there are sixty seconds in a minute...2011-12-14

    Is the wheel rolling along the ground? Or just rotating about a fixed axle? In the first case, the distance covered depends on the initial position of the point.2011-12-14
