Copy of Arc length: Quick Investigation
Original creation of this applet goes to Jennifer Silverman (derived from this worksheet.)
Interact with this applet for a few minutes, then answer the question that follows.
Is there any relationship among the length of the arc, the measure its corresponding central angle (shown in radians), and the radius of the circle? If so, describe.
If you cannot remember exactly how to describe the concept of a radian, please refer here.
