WebJul 3, 2024 · In technical terms, a sector is a part of a circle enclosed by two radii and the connecting arc, notes study.com. The formula for finding the area of a sector is: A = (Sector Angle / 360) * (π * r^2) Using the … WebArea of the segment = area of the sector- area of the triangle. = 100 sq. ft. - 78 sq. ft. = 22 sq. ft. Therefore, the area of the segment is 22 sq. ft. Example 3: Find the area of the major segment of a circle if the area of the corresponding minor segment is 62 sq. units and the radius is 14 units. Use π = 22/7.
