Volumes of Revolution Disc and Washer Methods Calculus Lesson:Your AP Calculus students will use integration to find the volume of a solid by disc and washer methods revolved around both the x-axis and y-axis. Volumes rotated about a line are provided as a separate lesson. Your students will have g.
Volumes of solids of revolution. A solid of revolution is obtained by rotating a curve about the x-axis. There is a straightforward technique, using integration, which enables us to calculate the volume of such a solid. Video tutorial 33 mins.

We can approximate the volume of this solid of revolution by partitioning it into n rectangles, and then summing the volume of the resulting n circular disks. This is just a Riemann sum. Thus, the volume is given by limit of the sum as the width of the rectangle approaches zero.
Function Revolution: This activity allows the user to find the volume and surface area of various functions as they are rotated around axes. This applet can be used to practice finding integrals using the disk and washer methods of calculating volume.
Solid of Revolution - Finding Volume by Rotation Finding the volume of a solid revolution is a method of calculating the volume of a 3D object formed by a rotated area of a 2D space. Finding the volume is much like finding the area, but with an added component of rotating the area around a line of symmetry - usually the x or y axis.
