calculation surface of bottom bombed

[mir]

Good evening,
imagine the classic tank bottom under pressure; I would like to get the surface of the bottom ... I have the profile-> I created the solid with the revolution -> I exploded the solid in the surfaces and I tried to convince the cad (with the command area) to give me the area of one of the surfaces ... but I did not succeed.

Do you know other methods?

Thank you.

There is an empirical way, which gives you with a certain degree of approximation the surface

creates another foundl, say 1cm larger than the first. You will remove from this your initial melt. you will get a solid melt of 1cm thickness. ask massprop the volume, divide it by your cm and you will have the superfice in the axle.

or google the formulas to calculate the surface of a spherical cap (I imagine it is a spherical cap. . )

Unfortunately it is not a spherical cap but a set of different curved rays.

Sorry but I already have the sheet metal bottom (of 3 mm thick) ... for what should I divide the volume that comes from massprop?

I found a very trivial solution... the revolution I create it not on the thickness but on all the volume (i.e. I do not make the revolution of the sheet section but the revolution of all a bottom line). I now find myself with a nice volume of the whole bottom ... I ask the area and incredibly is given to me by cad ... so I subtract the circular surface above (pigro x r^2) and get my beautiful bombed surface .... Not cool?

the streets of the cad are endless, as you see.
you found the most effective way alone. you just needed to consider the problem from a different angle
