CONES cannabis or cannabis smoking, referring to the cone piece used in a smoking device. CRACK In Australia this term is generally used to describe **crystal methamphetamine**. In the United. States, “crack” refers to crack cocaine, however crack cocaine is extremely rare in Australia.

A cone has one face, but **no edges or vertices**. Its face is in the shape of a circle. Because a circle is a flat, plane shape, it is a face. But because it is round around the outside, it does not form any edges or vertices.

A (finite, circular) conical surface is a ruled surface created by fixing one end of a line segment at a point (known as **the vertex or apex of the cone**) and sweeping the other around the circumference of a fixed circle (known as the base).

Here are some examples of cones in daily life: **Ice cream cone**. Funnel. Christmas tree.

**Examples of Cone**

- Party hat.
- Ice cream cone.
- Funnel.
- Traffic cone.
- Waffle cone.
- Megaphone.
- Christmas tree.

Properties of Cone**A cone has only one face, which is the circular base but no edges**. A cone has only one apex or vertex point. The volume of the cone is ⅓ πr^{2}h. The total surface area of the cone is πr(l + r) The slant height of the cone is √(r^{2}+h^{2})

cone, also called strobilus, in botany, **mass of scales or bracts, usually ovate in shape, containing the reproductive organs of certain nonflowering plants**. The cone, a distinguishing feature of pines and other conifers, is also found on all gymnosperms, on some club mosses, and on horsetails.

1a : **a solid generated by rotating a right triangle about one of its legs**. — called also right circular cone. b : a solid bounded by a circular or other closed plane base and the surface formed by line segments joining every point of the boundary of the base to a common vertex — see Volume Formulas Table.

Your genes **contain instructions that tell your cells to make molecules called proteins**. Proteins perform various functions in your body to keep you healthy. Each gene carries instructions that determine your features, such as eye colour, hair colour and height. There are different versions of genes for each feature.

A cone is **a distinctive three-dimensional geometric figure that has a flat surface and a curved surface, pointed towards the top**. The pointed end of the cone is called the apex, whereas the flat surface is called the base.

A cone has **a circular base attached to a curved face that wraps around and narrows into a point.** **From the side, a cone looks like a triangle**. Objects that are shaped like cones include party hats and funnels.

A cone is **a three-dimensional geometric shape that narrows from a flat circular base to a single point called apex or vertex**. In other words, a cone can be formed by joining an infinite number of slanting lines to the circumference of a circle from a single point called the vertex.

Lead students to see that a cone has no edges (at least no straight ones!), but **the point where the surface of the cone ends is called the vertex of the cone**.
