Homework #5 Question 4

Posted in Math by pgadey on 2018/07/20

Consider a solid ball of radius R. Cut a cylindrical hole, through the center of the ball, such that the remaining body has height h. Call this the donut D(R,h). Use Cavalieri’s principle to calculate the volume of D(R,h). Calculate the volumes of D(25,6) and D(50,6).


Several students have asked what D(R,h) looks like. Here are some pictures that I found to illustrate the concept. The donut D(R,h) is the region between the red sphere and blue cylinder. The golden balls below show various views of the donut. The donut should fit between the two planes z=h/2 and z=-h/2, so that it has total height h.

Malin Christersson’s Cube Toy

Posted in Math by pgadey on 2018/07/11


I was looking through the Geogebra site and found this lovely applet Orthographic Projection by Malin Christersson.

This is a lovely tool for investigating one of my favourite facts about hexagons:

The area maximizing orthogonal projection of a cube is the regular hexagon.

It turns out that Malin has tonnes of awesome geometry stuff online!

Awesome math art!
