For each of the following angles, assume that the terminal ray of the angle opens up in the counter-clockwise direction a.
a) a circle with a radius 8 cm long is centered at angle a's vertex, and angle a subtends an arc length of 88 cm along this circle.
-the subtended arc is how many times as long as the circle's radius?
- therefore, the radian measure of angle a is?
b) a circle with a radius 18 cm long is centered at angle b's vertex, and angle b subtends an arc length of 72 cm along this circle. what is the radian measure of angle b?
c) a circle with a radius 3 inches long is centered at angle c's vertex, and angle c subtends an arc length of 1.1781 inches along this circle. what is the radian measure of angle c?
