Domain restriction of functions with three variables, e.g. a sphere

When I try to create a hemipshere by restricting the domain of a sphere by using

If[0<=z, x^2+y^2+z^2=1]
Geogebra gives me an error.

Are there any other ways to do this and is this meant to be implemented this way?

you can do sqrt(1-x^2-y^2)
