1. Sector Area and Arc Length

2. • Arc length is the distance along an arc measured
in linear units.
• Arc length is shown as

3. • Example: Find each arc length. Give your
answer in terms of π and rounded to the
nearest hundredth.

4. • A sector of a circle is a region bounded by two
radii of the circle and their intercepted arc.

5. • A segment of a circle is a
