This math topic focuses on the calculation of the area of a "donut" shape within a circle using the radii of the internal and external circles. As a subset of Geometry, specifically Circle Area, Sectors and Donuts, it involves exercises where learners must find the area of the shaded region or "donut," given the outer and inner radius of the circles. This involves the application of the mathematical constant π (Pi) in determining the solution.
