How to Find Volume by Spinning: Disk Method

The Disk Method calculates volumes by revolving a region around an axis, forming disks. Integrating these disk areas, perpendicular to the axis of revolution, yields the solid’s volume. It’s ideal for solids with simple, symmetric shapes, where the radius varies along the axis, allowing precise volume calculation through continuous addition of infinitesimally thin disk volumes.
