Find the average angular velocity (in rad/s) of a wheel of radius 30.0 cm that starts from rest and makes 6.00 revolutions in 2.50 s.

This is my work, but the answer I am getting is not correct:

w avg = angular displacement / time
= 6.00 rev * (2π rad / 1 rev) / (2.50 s)
= 15.079644 rad / s
= 15.1 rad/s
