A circle has radius 3 centimeters. Suppose an arc on the circle has length
What is the measure of the central angle whose radii define the arc?
What is the scale factor?
What is the length of the highlighted arc in circle A? (use keyboard and NO units)
What is the length of the highlighted arc in circle B? (use keyboard and NO units)
What is the ratio of the arc lengths?
Match each arc length and radius with the measure of the central angle that defines the arc.
