Hi, everybody.

Is this tank an ellipsoid?
If not, what shape is it?

That is not an ellipsoid, that is a cylinder with semispherical ends.

It breaks down to the volume of a semi-filled cylinder of length L and radius R**plus** the volume of a semi-filled sphere of radius R.

Uh ... I went looking for the relevant formulae but ended up finding a calculator that does precisely what you want:

Be careful with your numbers:

- you're asked for the**radius** which is only half the diameter of the tank

- you're asked for the length of only the**straight** part
