## Homework Statement

[/B]

A vertical cylindrical container contains 5590 gallons of gasoline and is 1.38 m in radius. Due to evaporation within the tank, the pressure on the top of the fluid is 2.5 times normal atmospheric pressure. The density of gasoline is 737 kg/m3

## Homework Equations

## The Attempt at a Solution

[/B]

converted gallons to Liters: 5590 gallons x 3.785L/1 gallon = 21160 L

Found the height of cylinder: V

_{cylinder}= πr

^{2}h

21160/(π×1.38

^{2}) = 3536m

Solve for Pressure using P = P

_{o}+ ρgh

= (101300 Pa × 2.5) + (737×9.8×3536)

Plugged it all in and it was...wrong. :-/

Only thing I suspect may be wrong is the units I'm suppose to be using ( cm instead of m for example ). Or the possibility of the cylinder being closed when I assumed it was open. But everything else to me looks good. Please help.
