4. Discuss Volumes of Regions with Known Cross Sections
Most of the volumes that we have done had circular cross sections. Occasionally, you may have figures whose cross sections are squares, triangles, etc. It is just an extension of the Disk Method.
In order to find the volume with the disk method, you integrated the area of one cross section. Because the cross section was circular, you integrated the formula for the area of a circle (pi r squared). So, if a new problem has squares as cross sections, you will integrate the formula for area of a square (side squared).
Example: Let R be the region in the first quadrant under the graph of
Find the volume of the solid whose base is the region R and whose cross sections (cut by planes perpendicular to the x-axis) are squares.
