The shaded area of the graph of an inequality show the solution to the inequality. For example, if the area below y = x is shaded it is showing those ordered pairs which solve y < x.
The formula to find the area of the segment is given below. It can also be found by calculating the area of the whole pie-shaped sector and subtracting the area of the isosceles triangle △ACB.Formula for the area of a segment of a circle where:C is the central angle in DEGREES R is the radius of the circle of which the segment is a part.π is Pi, approximately 3.142sin is the trigonometry Sine function.

A line segment that divides a circle in two is a chord.If the two parts of the circle are equal, the line segment is a diameter.See 'The Parts of the Circle' in Sources and related links, below.
Area of any circle = pi*radius squared
