cone
A cone or a paraboloid
A solid figure that can be made with a net of 4 triangles is a tetrahedron. A tetrahedron consists of four triangular faces, which can be arranged in three-dimensional space to form a three-dimensional shape. Each triangle in the net corresponds to one face of the tetrahedron when folded together.
To determine what solid can be formed from a given net, one would typically look for the arrangement of faces, edges, and vertices indicated in the net. If the net features a specific combination of triangles and rectangles, it could represent a pyramid or a prism, depending on the arrangement. Without seeing the net, it's difficult to specify the exact solid, but common solids formed from nets include cubes, pyramids, and prisms. Identifying the base shape and the number of faces will help clarify which solid can be constructed.
That sounds like a cone. One surface is a circle and the other surface is curved.
There is no solid that has those characteristics. To have an edge it must have another surface.

I dont' now jajjajajajajajsjajaj

An open circle should have a dashed circumference, a closed circle a solid one.

semi-circle
No, not every solid has only one net. A net is a two-dimensional representation of a three-dimensional solid that can be folded to form the solid. Many solids can have multiple nets due to different ways of arranging their faces and edges. For example, a cube can be represented by several distinct nets, each composed of six squares arranged in different configurations.

a cone...
Circles were drawn by ancient peoples before writing was developed. No one "invented" or "made" the circle from that perspective.
A circle comes to mind as the face of a right cylinder (which has 2 faces). The curved side is not considered a face.
