📌The disk and shell methods are techniques used to find the volume of a solid formed by rotating a region around an axis. The disk method slices the solid into thin, flat disks perpendicular to the axis of rotation, and adds up their volumes. The shell method, on the other hand, uses cylindrical shells formed by slicing the region parallel to the axis. Each method is useful depending on the shape of the region and the axis of rotation, helping to simplify volume calculations in calculus. 📌Supp
