Round calculations? Didn't get past Business Math in school....and pretty much don't remember what I learned yesterday so....Domes are fairly simple, you just need a few more measurements. If it is near spherical just use the round calculations and subtract one half. If it is really oblong then Google dome volume .....there are many calculators out there.

Hola Dave,CB, morning...... PM's actually deprive others from learning.... not trying to be an a$$, this is a learning forum.....
There is a simple way of calculating the dome volume. The dome shape is called an oblate spheroid (flattened ball!) and the volume can be calculated using the formula V =0.5×0.75×PI×R×R×H. Using diameter instead of radius and simplifying we get
V = 0.52 × D × D × H, where D is the tank Diameter and H is the dome height measured from the weld seam.
If we are not too worried by details and can accept a 4% calculation error we can simply use
V = D×D×H/2
Or, for both domes in one
V = D×D×H
More info on spheroids can be found at https://en.m.wikipedia.org/wiki/Oblate_spheroid
