Question

A washer contains a drum that spins at 750 revolutions per minute. To the nearest hundredth, the angular velocity of the drum is _____ radians per second.

Answer 1

For this case, the first thing we must do is to take into account the following transformation of units:
 1 revolution = 2pi radians
 1 minute = 60 seconds
 Applying the transformation of units we have:
 $(750) * (1/60) * (2 * pi) = 78.54 rad / sec$
 Answer:
 To the nearest hundredth, the angular velocity of the drum is 78.54 radians per second.
