how do i find the surface area of a dome?
i've tried list, area and massprop commands but yielded no result.

What kind of dome? Solid model? Surface? Wireframe? ??

There exist exactly math formulas for spheres.
Try them
Good luck

2*pi*r*h; r is radius of the sphere, h is height of the dome.

thanks for your reply. forgot to mention about the dome profile which is
irregular (series of arcs).
first i made a region and revolved it and came up with a solid dome. how do
i find the surface area without using mathematical formulas?

How about the AREA command? It will return the entire surface area of your
solid, so if your dome has a flat bottom, you can subtract the area of the
circle(?) that constitutes its base; what's left will be the area of the
dome.
