ClipArt images of cones, which are three-dimensional geometric solids that are made by taking all straight lines from the apex (top) at an angle to a plane in a 360 degree radius. A cone has a circular base, and looks like a triangle when viewing them from only the x and y axis.

"The contours of a concave (hollowed out) cone are close together at the center (top), and far apart at the outside (bottom)." — Moss, 1914

A cone is a solid whose base is a circle, and whose convex surface tapers uniformly to a point called the vertex. If a straight line be drawn on the cone from the vertex to the edge of the base, this line is ccalled the slant height.
