Definite integrals allow us to solve problems involving the accumulation of change in area or volume over an interval. Calculate volumes of solids of revolution using definite integrals. Volumes of solids of revolution around the x- or y-axis whose cross sections are ring shaped may be found using definite integrals with the washer method. Volumes of solids of revolution around any horizontal or vertical line whose cross sections are ring shaped may be found using definite integrals with the washer method.
