Arc Length and Sector Area

Unit 6: Trigonometry: Circles
Lesson 13 of 17

Objective: Students will be able to practice finding arc length and sector areas for different radius lengths and central angle measures, laying groundwork for a definition of radian measure in the next class.

Big Idea: Students find their friend similarity lurking in a table of repeated calculations. A firm concept of radian measure follows close behind.
