This topic covers the calculation of the total area of a circle based on the given area of a shaded sector and invites students to use their understanding of the relationship between a sector's area and the circle's total area. Learners solve multiple-choice questions where they are tasked with identifying the total area of the circle from the provided area of a sector and a list of possible circle areas. The questions enhance intermediate level geometry skills focused on circle properties, particularly sector calculation.
