How many cubic meters in a cylinder?

  1. Sep 13, 2012 #1
    1. The problem statement, all variables and given/known data

    Given a cylinder of radius = 5m, and height = 10m, how many cubic meters is that? If I just compute those values in the formula for a cylinder, I get 785.4. But 785.4 what? Is it785.4m^3?

    2. Relevant equations



    3. The attempt at a solution

    Yes, you have a ##\pi r^2h## which dimensionally is ##m^3##.

    Yes, look at the formula for volume:

    [tex]V = \pi r^2 h[/tex]

    The units of both r and h are meters, so the units of volume are (meters)^2 * meters = (meters)^3.
