Gabriels' Horn - aka Torricelli's Horn - is one of my favorite examples in Calculus. This is a region of revolution where the surface area is infinite but the volume is finite. How cool is that! In this video we recall the formulas for surface area and volume of regions of revolution and compute out the improper integrals, in one place having to apply the Comparison Test.

YOUR TURN! Learning math requires more than just watching videos, so make sure you reflect, ask questions, and do lots of practice problems!
