Solids of revolution are 3D shapes created by rotating a 2D curve around an axis. Calculating their volumes is done using disk and washer methods, integral to calculus and geometry. These methods are crucial for understanding the transition from planar figures to volumetric forms and have practical applications in various fields, such as engineering and design. By integrating the areas of circular cross-sections, mathematicians can determine the precise volumes of even the most complex shapes.
