Creating the top of a sphere as an area

Hello, I just want to have the top of a sphere as an area. How do I do that? I tried to create a sphere then I cut it with a plane in a specific height , but then I didnt knew how I will get my Volume to an area …

Appreciate any help

Hi Robin,
If you cut your sphere with a plane, then you should be able to run the area command and select that top of the sphere.
To get the volume of that new object, run the cap command on that bit of sphere, making it a closed polysurface, and run the volume command on that.
