Volume of a cone by integration

  1. Oct 14, 2004 #1
    Can anyone help me with this question?

    A uniform solid cone of height b and base radius a stands on a horizontal table. Find an expression for the volume of the disc at height h above the base. Integrate over all the discs to show that the total volume, V, is given by V =pi/3 * b * a^2
