A cylinder, a doughnut with a slice cut out by radial planes, a sphere with two slices removed (possibly in a wedge shape), a cone with its top and bottom cut off by horizontal planes, a paraboloid with top and bottom cut off by horizontal planes.
An hemisphere is half of a globe with a circular flat base, a round edge, a curved surface but no vertices.

Euler's definition do not apply to curved solids. faces must be polygons; they cannot be circles. using the conventional definitions of faces, edges and vertices, This question causes frustration for teachers and students. Euler's definitions of edges, faces and vertices only apply to polyhedra. Faces must be polygons, meaning comprised of all straight sides, edges must be straight, and vertices must arise from the meeting of straight edges. As such, a cylinder has no faces, no edges and no vertices, using the definitions as they apply to polyhedra. You need to create a different set of definitions and understandings to apply to solids with curved surfaces.
Faces: 2 circular, 1 curved rectangular. Vertices (not vertexes!): None Edges: 2 circular.

None, they have vertices.
Both.
No but it does have a pair of circular parallel edges.
