   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.
