Chapter 12 : Area Related to Circle

This chapter transitions from basic circle properties to calculating the areas of specific portions of a circular region, namely the Sector and the Segment.

Key Points (Sector and Segment)

Sector: The region enclosed by two radii and their corresponding arc.
Minor Sector: The smaller portion (e.g., OAPB).
Major Sector: The larger portion (e.g., OAQB).

Segment: The region enclosed between a chord and its corresponding arc.

Minor Segment: The smaller portion (e.g., APB).
Major Segment: The larger portion (e.g., AQB).

Core Formulas

The chapter utilizes the Unitary Method based on a full circle's angle to derive these essential formulas:
