A wheel completes 3.6 revolutions in 6 seconds.

What is the angular velocity of the wheel in radians per minute?

1 - 3.6 revolutions per 6 second =3.6 / 6 =0.6 revolutions/sec.
2 - Using 1 revolution = 2*pi radians
3 - 0.6 revolutions/sec * 2*pi radians =3.7699 radians/second.
4 - 3.7699 radians/sec x 60 seconds =226.2 radians/minute.
