A cyclinder cooling tank has an outside diameter of 6.00 ft. the wall on all sides are 5.00in thick and the tank is 10.0ft tall. how many gallons of water will this tank hold?
the inside radius is r=(3 - 5/12) ft
So, its volume is πr^2 h
Just plug in your numbers. That will give you the volume in ft^3. Then just apply the conversion factor for gal/ft^3.
