The math topic focuses on calculating the area of a circle sector given the arc length and the radius of the circle. It is a specialized Geometry section dealing with circle area, sectors, and related problems (termed as "Sectors and Donuts - Intro"). The participants are provided with specific arc lengths and radii for various questions, and they must apply the related geometric formulas to determine the area of the shaded sectors, expressed in terms of π. Each question has multiple choice answers, requiring calculation and understanding of circle geometry to select the correct option.
