What angle measure, in radians, corresponds to −0.6 rotations around a unit circle? (Round your answer to two decimal places.)
The book gives the answer (-3.77) but not the process of how to get to the answer; it's really frustrating.

Kathryn,
Each rotation turns 2pi radians.
So, -0.6 rotations turn -06*2pi = -3.77 radians <==Answer
I am from AZ too.
Good luck!
Robert is correct but just for a little more detail:
one full rotation of any circle (meaning the unit circle included) has an angle measure of 2pi radians, when they say -.6 rotations they mean .6 of a rotation in the negative angular direction, thus as Robert writes
(-.6)(2pi)= -3.77
