The shape you are describing is a cylinder. A cylinder has two flat circular faces (the top and bottom) and one curved surface that wraps around the sides. It has no edges or vertices where flat surfaces meet, as the curved surface is continuous.
The cylinder only has 2 faces which are flat but the sides are curved.
The shape you are describing is a cone. A cone has one flat circular base and one curved surface that tapers to a sharp point at the top. It does not have any sides, which aligns with your description, and it resembles a party hat in appearance.
a solid with flat sides meet at sharp edges and corners is called crystal structure
A hemisphere
No. A sphere is curved with no corners and it is not flat.A circle could also be considered curved with no corners but flat.
a circle
A cylinder.
Assuming there are no curved sides, it is a decahedron. It is likely to be an octagonal prism but there may be other configurations.
Irregular shape is the term given to an object which has 1 flat side, 1 curved side, no corners but has curved edges.

A sphere. A sphere is a solid figure that has no faces, edges, or vertices. This is because it is completely round; it has no flat sides or corners.
