Calculating Areas Related to Circles
Building on the properties of circles, this chapter deals with mensuration. Areas Related to Circles teaches students how to calculate the area of specific parts of a circle, namely Sectors and Segments. Students learn to derive and apply formulas involving the central angle ($theta$) to find the area of a sector and the length of an arc.
The chapter also covers finding the areas of combinations of plane figures, which might involve circles combined with triangles, squares, or rectangles. This requires a strong understanding of geometry and careful calculation. These concepts are practical and are frequently used in design, architecture, and land surveying where curved boundaries are common.
