Sxsmachie's answer is correct,
I would add that from a volume standpoint the spherical shape is best from the point that: for a given amount of surface material a sphere has the most internal volume, next would be cylinders with hemi-spherical ends.
Spheres have no mechanical stress points and are very strong. Look at deep sea vehicles they are round, or submarines are cylinders with hemi-spherical ends. Maximum volume and able to withstand high internal and external pressures.

Cylinders are economical to construct, since bending metal around a single axis is easy to do. Small fuel tanks, such as those in an automobile, can be made by pressing steel on molds the same way that the car's body is built, and such tanks are rarely cylindrical: the tank is made in a shape that can fit in the space available.

If you consider the cylindrical portion:-
From the radial center you measure equal distance (the radius).
Thus the pressure exerted on the side of the tank stays equidistant from the sides causing equal pressure on the cylindrical shapes sides (balanced pressure).
If the shape was cubic the distances to the corners would be longer that rectangular to the sides, thus more pressure on the rectangular distances causing the cube to be come spherical (pressure on rectangular distance try to balance out to distance to corners).
End caps of tank is semi-spherical in shape due to above explanation of cube.
Speres aren't used because of difficulty in handling (poor center of gravity compared to cylinder laying flat (longitudinal).

They are cylinderical because when you press on one side of it, it effects the whole thing. It's a very strong shape and requires alot to break it. Think of your body, you have someone pull one are and it's going to affect your whole body. Well the same with this tank, it's just really stable.

because they allow the liquid to flow back and forth when the tank is having turbulance alot more smoothly then if it were a box. If it's a box the fuel starts slamming into the right angles creating and disturbing the fuel a great deal more which could hurt the mixture or cause it to ignite.

a cylinder because of it's shape holds more strength. A box has week points at the corners.

I would say probably because they are easier to clean out that way. Less chance of stuff sticking in corners. That's my guess though.

Goal is not have sharp edges as they are more prone to building up charge and can give up a spark.

It's a question of strength, there is an equal load on all sides.

cylinders store liquids better then cubes. spheres store liquids the best but dont stand up too well.
