How many cubic meters in a cylinder?

  • #1

Homework Statement



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?

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.
