**drwls**, Saturday, December 29, 2012 at 11:07pmThe volume in ft^3 is

(pi/6)*D^3

if you use D = 11.4 ft

You do the conversion to gallons.

For the accuracy they desire, they should NOT be telling you to use 7.5 gal/ft^3 as the conversion factor and pi = 3.14.

I have no idea what you are using the symbol r for pi.
