Convert the radian measure to degree measure. Use the value of π found on a calculator, and round answers to two decimal places.

A) -570°

B) -1140π°

C) -285°

D) -9.94°

Answer 1

The formula to convert y radians to x degrees:


`x^o=(180^o y)/(\pi)`

We have:


`y=-(19\pi)/(6)`

substitute:


`y=(-(19\pi)/(6)\cdot180^o)/(\pi)=-(19)/(6)\cdot180^o=-19\cdot30=-570^o`

Answer: A. -570°

Answer 2

=  (-19)* pi / 6  * 180 / pi   = -570 degrees
