A solid angle, measured from a vertex, is the ratio between the area subtended by the angle at the vertex and the the square of the distance to the vertex. The unit of measurement is the stradian.
The solid shape you are describing is called a cone. A cone has a circular base and narrows to a single vertex, or apex, at the top. Its curved surface connects the base to the vertex, distinguishing it from other solid shapes.
