A sphere An ellipsoid A hyperbolic paraboloid
A sphere, a cone, a section of a sphere or ellipsoid, a torus (doughnut) sliced by a plane perpendicular to its axis, a paraboloid. These are some examples.
A sphere intersected by a plane, which could be a hemisphere. Alternatively, a cone, or a paraboloid.
If you have one flat face and I have one curved face, which one of us is the 3d shape? Anyway, a 3d shape with pne f;at, circular face and one curved face could be: a section of a sphere or a section of an ellipsoid cut by a plane parallel to one of its axes, a section of a paraboloid or a cone. There are probably other shapes.
The cross section of a paraboloid, when sliced parallel to its axis of symmetry, is a parabola. If the slice is made perpendicular to the axis, the cross section can be a circle or an ellipse, depending on the orientation and position of the cut. The specific shape of the cross section will vary based on the location and angle of the slice in relation to the paraboloid.

A Circle if you mean 2d circle, 3d sphere =P Any continuously curves shape has no sides; ellipse (ellipsoid), cone, hyperbolic paraboloid...

Sphere, cylinder, paraboloid.

either a semisphere or a hemisphere

There are several options that depend on the definition of a "side of face". An infinite cone a paraboloid a semi-hyperboloid an ellipsoid a spheroid are some examples. And, last but not least, a smooth blob.
The shape is a paraboloid. In a paraboloid, all waves that come from infinity (or from far, far away - this is practically the same for the geometrical considerations) will be reflected in such a way that they gather at a single point.
It depends on the 3d shape.
It is not a 3D shape.
The answer will depend on the shape of the dome. If it is a hemisphere, then the voume is 2/3*pi*r3. But it could be paraboloid or ellipsoidal in shape.
