Solutions and comments for Quiz 3 from today

REVIEW PROBLEMS FOR 6.2 (MORE TO BE POSTED FRIDAY): 1,5, 9,11
A few review problems have also been posted in Webwork (do homework set "volumes by shells").

9/3/2013
Today we discussed volume of solids using slicing
PRACTICE PROBLEMS FOR VOLUMES BY SLICING POSTED ON WEBWORK
REVIEW PROBLEMS: 6.1 PROBLEMS 5,7,12, 19,23,33,45,47,59
Basic idea is to find volume by "adding up" the volumes of the slices obtained by slicing the solid perpendicular to the x or y axes
For solids that are circular in cross-section (solids of revolution), the slices will look like disks or washers
We did problem 11 (volume of tetrahedron) from book. I also reviewed the calculation of the volume of the cone. It is interesting how both of them are one-third of the volume of the "completed solids" -- the prism and the cylinder -- respectively
Here are two links to visualize why that is so:
TETRAHEDRON AND PRISM
CONE AND CYLINDER

8/30/2013
