Area and Volumes of Revolution

Disk Method: The disk method is a technique used to find the volume of revolution by considering the cross-sections of the solid as disks or washers perpendicular to the axis of rotation.

Shell Method: The shell method is an alternative technique for finding volumes of revolution. It involves considering cylindrical shells parallel to the axis of rotation and integrating their volumes.

Washer Method: The washer method is another approach for finding volumes of revolution. It uses washers (rings) instead of disks or shells, allowing for more complex shapes to be calculated.
