The following page contains animated visualization of volumes by cross-section and volumes of revolution for various questions from section 7.3 from the Calculus book by Finney, Demana, Waits, & Kennedy. All graphics were created using Mathematica and the accompanying Mathematica notebooks are available for download (Mathematica 5.2). Students of Mr. Evans' AP Calculus AB course, after the AP test in 2007, created the majority of these graphics.
