Segment Area in Circles Quicker Methods

Using alternative area formulas for triangles like Heron's Formula and the Area of an Oblique Triangle formula I work through two examples of finding the area of a segment in a circle. EXAMPLES at 3:30 7:49 NOTE: As you can read by the title we are finding Segment Areas, so please ignore the 5 or 6 times in this lesson I say sector area when I should be saying segment area!!!
