MATSEC AM Pure Mathematics Complete Prep Course — Lesson 47: Arc length, sector and segment area

Lesson 47 drills the radian-only formulas for circular sectors. It covers arc length s equals r theta, sector area one half r squared theta, segment area one half r squared times theta minus sine theta, and the chord two r sine of theta over two. It also covers sector and segment perimeters, degree conversion, the arc-over-area shortcut giving two over r, and shaded-region subtraction problems.
