question for a math wiz?

[Charlie B]

I'm going to do this without googleing, just to see how close I am. The area of a circle is Pi X radius squared so the 29 ft diameter tank would have a 14.5 ft. radius. That would be 210.25 X 3.1416 =660.5214 X 29 (length=19155.12 cu ft X 8 gal per cu ft =153240.9648 Gallons
Am I close?
