How much would a swimming pool with the following dimensions weigh?
9 foot diameter (round pool), 26 inch water height.

Thanks!

Seems simple enough but I fail to come up with consistent answers. My math would be to multiply the diameter by pi and then that result by the height. The I have to multiply by something else. As I type this I seem to remember pi * r^2 (radius and not diameter!). Aww crap. Gotta run now though. It seems the patio that my friend decided would be a good option is heaving something awful and I might have to let the water go!
