In the given figure, what is the region that is shaded in green called?
Green – Major Sector, Orange – Minor Sector
In the given figure, the region shaded in green is bounded by an arc (AB) and two radii (OA and OB). Thus it is called a 'sector'.
Since the region shaded in green occupies a greater area compared to the region which is shaded in orange, thus it is the major sector.
