Assignment for Monday, June 2, 2008

Due Tuesday, 6/3/08

Worksheet 12.5 Practice A on volume of pyramids and cones.  You may do the entire sheet, but I am only assigning problems #1-4, 6-16 even, 9, 17, 20, and 25.

Notice that the fraction for two-dimensional pyramid and cone measurements (area of triangles, surface area) is 1/2, while the fraction for three-dimensional pyramid and cones measurements (volume) is 1/3.  Hmmm: 2-D is 1 over 2, 3-D is 1 over 3.  Coincidence?  I think not.

Tuesday we cover spheres with surface area, then determine the volume of that which we have covered.

Wednesday we look at ratios of lengths, areas, and volumes so more.

Also on Wednesday, a quiz covering volume of prisms, cylinders, pyramids, and cones.

Thursday is for review, then Friday we’ll take our last chapter test of the year.  Yippee!
