There are many possible answers:
A cone
A sphere from which a slice has been removed
An ellipsoid from which a slice has been removed
A paraboloid from which a slice has been removed
The description given fits that of a cone
Circle
The answer is - a cone.
it is a three dimensional cone , the circle is the edge of the figure and the curved side is the body of the cone, the vertex is the point of the cone
Don't know. It cannot be a cone since that has two faces: one curved (curvered?) face and one flat (circular) face. Alternatively, an infinite cone has only one curved face but then it has no edge.
a circle has one face, no vertexes ( or point ), and one curved edge
The description given fits that of a cone
One continuous curved edge

2D = semi circle 3D = hemisphere
A circle?
one face one vertex and two circle edges * * * * * What kind of cone is that? It has 1 edge, 2 faces (one curved and one plane), and 1 vertex.
It could be a semi-sphere but mostly it's a cone.
A circle has one curved line and it is its circumference
