In mathematics, the disk method is a technique used to calculate the volume of a solid generated by rotating a curve around an axis. The idea is to imagine slicing the solid into very thin circular disks perpendicular to the axis of rotation. Each disk has an area that depends on the distance from the axis, and by summing the volumes of all these disks, we approximate the entire solid. This process is formalized using integration, where the radius of each disk comes from the function being rotat

📌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
