Both.
A truncated cone has two circular edges (the top and bottom bases) and a curved lateral edge that connects these two bases. The top base is smaller in diameter than the bottom base, creating a frustum shape. The lateral edge is formed by the sloped surface that connects the two circular edges. Overall, it features both linear and curved edges.
A cylinder has two curved edges, which are the edges where the curved surface meets the two circular bases. In addition to these curved edges, a cylinder also has two flat circular faces but no sharp edges.
Three types of solids that do not have any faces or edges are spheres, cylinders, and cones. A sphere is perfectly round and has no edges or vertices, while a cylinder has curved surfaces but flat circular bases. A cone features a circular base and a curved surface that tapers to a point, but it also lacks distinct edges and faces.

A cone has a curved base edge and 1 vertex
A cone has one circular face. It only has one vertice and it does not have any edges since the face is circular.
The shape of the face on a cone is a circular base at the bottom and a curved surface that narrows smoothly to a point called the apex. This curved surface is referred to as the lateral face of the cone. Overall, a cone has one circular face (the base) and one curved surface.
A solid figure with one circular base and one curved surface is called a cylinder. In a cylinder, the circular base is parallel to the other circular base (if there is one), and the curved surface connects the edges of the base, forming a three-dimensional shape. If it has only one base, it can be considered a cone, which has a circular base and a single curved surface that narrows to a point.
