Mathematics
Sector
In Class 9 Mathematics, the Circles chapter introduces the sector as the region enclosed by two radii and the arc between them. Students learn to identify minor and major sectors, relate a sector’s central angle to the complete angle at the centre, and connect it with the corresponding arc, circumference, and area of the circle. They use these relationships to interpret diagrams and solve problems involving sector angles, arc lengths, and areas.
