+511 1. What quadrant does the terminal side of the angle -230° lie?
2. A circle has an arc length of 32π that is intercepted by a central angle of 240°.
What is the radius of the circle?
+36916 1. -230 degrees = +130 degrees = quadrant II
2. Circumference = pi * d
32pi = 240/360 pi *d
32 (360/240) = d = 48 r = 1/2 d = 24 units
