Homework Help: Volume of a conic section

  1. Mar 12, 2007 #1
    I would like to know if an equation exists for the volume of a section of a cone. For example, a conic shaped tank lying on its side with the point to the left and the circular base to the right is filled partially with liquid. The height of the liquid, volume of the cone, length of the cone and the base radius of the cone are known.

    * ----------

    * * R
    * __________* ____ | __ liquid level
    * * | |
    * * h |
    * ----------
    |-------- H ---------|

    How would you find the volume of the liquid in the tank?

    Thank you,

    I appologize, but when the message was posted it removed all the spaces in the drawing I made. I hope you will be able to provide an answer with the text description.

    There is no closed form formula for this geometry, you will need to use a volumn integral over the region of interest.
