Visualizing volumes by known cross section
Mr. Fahad
This applet will help you to visualize what's going on when we build a solid from known cross sections.
The "X" slider allows you to move the single cross section along the interval [0,1]
The "n" slider allows you to choose how many of each cross section will be displayed.
You can choose to view squares, equilateral triangles, or semi-circular cross sections perpendicular to the x-axis. You can also click on the 3D graph and rotate and revolve the view to get a better sense of what the solid looks like.
Enjoy
Mr. Fahad
