An electric motor turns at 2400 revolutions per minute or 2400 r/m.
Find the angular velocity, in radians per second, in exact form and in approximate form, to the nearest hundredth.

--------

This is what I've done so far and I don't know what to do next ...

2400 r/m divided by 60s = 40

---------

Answer: 80pi rad/s, 251.33 rad/s

  2. 2400 (rev/min)*(2 pi/radians/rev*(1 min/60 s)

    You do the multiplying and rounding off.
