cone

a geometric solid consisting of a plane base bounded by a closed curve, often a circle or an ellipse, every point of which is joined to a fixed point, the vertex, lying outside the plane of the base. A right circular cone has a vertex perpendicularly above or below the centre of a circular base. Volume of a cone: 1⁄3πr²h, where r is the radius of the base and h is the height of the cone.a geometric surface formed by a line rotating about the vertex and connecting the peripheries of two closed plane bases, usually circular or elliptical, above and below the vertex.See conic section

anything that tapers from a circular section to a point, such as a wafer shell used to contain ice cream

the reproductive body of conifers and related plants, made up of overlapping scales, esp the mature female cone, whose scales each bear a seed.a similar structure in horsetails, club mosses, etc.Technical name strobilus
