Answer 1

Sectors And Segments
A sector is the part of a circle enclosed by two radii of a circle and their intercepted arc. The segment of a circle is the region bounded by a chord and the arc subtended by the chord.

where n is the number of degrees in the central angle of the sector
where CS is the arc length of the sectorThe formula for the area of a segment of a circle:
The area of segments can also be solved using trigonometry:
