Washers, disks, and known cross sections don't need to be a pile of formulas.
This problem set focuses on visualizing the solid and understanding what each slice contributes to its volume. From there, the integral becomes much more natural.
Practice choosing the correct radius or cross-sectional dimension, setting bounds, handling inner and outer radii, and translating two-dimensional regions into three-dimensional solids.
Inside: 4-question diagnostic • disks & washers • known cross sections • radii & bounds • volume setup • AP-style questions • readiness check • complete solutions
