Area of sector
वृत्तखंड का क्षेत्रफल
In this Class 9 Mathematics topic from the chapter Area and Perimeter, students learn how to find the area of a sector, the part of a circle enclosed by two radii and an arc. They understand how the central angle determines the sector’s share of the full circle and apply the formula (θ/360) × πr² using the angle in degrees and the radius. Practice includes interpreting diagrams, substituting values, simplifying calculations, and solving related word problems.
