Identify cross-sections of 3D objects and solids generated by rotating 2D objects.

Determine cone dimensions from a rotated right-triangle region

Problem

A filled right triangle with legs \(a\) and \(b\) is rotated separately about leg \(a\) and about leg \(b\). Use the diagrams to identify \(\text{both}~\text{solids}\), their radii and heights, their slant heights, and whether their volumes must match.
