A high-speed sander has a disk 8.00 cm in radius that rotates about its axis at a constant rate of 1100 revolutions per minute. Determine the angular speed of the disk in radians per second.

    Just convert 1100 rpm to radians per second. The radius has nothing to do with the answer.

    100 rev/min * (1 min/60 s)*(2 pi rad/rev) = ___ rad/s
