   What is a sector in math?

   • A mathematical instrument, consisting of two rulers connected at one end by a joint, each arm marked with several scales, as of equal parts, chords, sines, tangents, etc., one scale of each kind on each arm, and all on lines radiating from the common center of motion. The sector is used for plotting, etc., to any scale.

   How do you find the area of a sector?

   • A Sector has an angle of θ instead of 2 π so its Area is : θ 2π × πr2 Which can be simplified to: θ 2 × r2 Area of Sector = θ 2 × r 2 (when θ is in radians) Area of Sector = θ × π 360 × r 2 (when θ is in degrees) The Area of a Segment is the area of a sector minus the triangular piece (shown in light blue here).

   How do you calculate area of a segment?

   • The Area of a Segment is the area of a sector minus the triangular piece (shown in light blue here). There is a lengthy reason, but the result is a slight modification of the Sector formula: Area of Segment = θ − sin (θ) 2 × r 2 (when θ is in radians) Area of Segment = ( θ × π 360 − sin (θ) 2) × r 2 (when θ is in degrees)

   There are two main "slices" of a circle: The "pizza" slice is called a Sector. And the Segment, which is cut from the circle by a "chord" (a line between two points on the circle).
