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
