WebA circular sector is the portion of a disk enclosed by two radii and an arc. A sector divides the circle into two regions, namely Major and Minor Sector. The smaller area is known as the Minor Sector, whereas the region having a greater area is known as Major Sector. WebSo the area of the sector over the total area is equal to the degrees in the central angle over the total degrees in a circle. And then we just can solve for area of a sector by multiplying both sides by 81 pi. 81 pi, 81 pi-- so these cancel out. 350 divided by 360 is 35/36. And so …
