This study guide covers the washer method for finding volumes of revolution around the x-axis. It explains when to use this method (when a gap exists between the region and the x-axis), how to calculate volume using the washer method formula with definite integrals, and common mistakes to avoid. It includes a worked example and practice questions, and defines key terms like volume of revolution.
