This math topic is centered on the geometry of circles, specifically calculating the total area of a circle from the area of a sector. For each problem, students are given the area of a shaded sector and must determine the full area of the circle from a set of multiple-choice options. This topic falls under an intermediate level geometry practice and helps to reinforce understanding of circle geometry and the relation between the sector and total area.
