Cone

By Daniel Smith and Eric Galatro

The 3 kinds of cones• There is a: cone, circular cone, and right

circular cone• cone: V = hB/3 is the formula and it has a cone

and it base is a circle• Circular cone: the base is a circle and it is like a

regular cone but this one has rough edges• right circular cone: V = Pi r2h/3 is the formula

and the axis is perpendicular to the base

Angles of a cone

• All cones have an angel in it.

• Even if the cone looks as it doesn’t it does in any direction.

• A cone has an acute angel and a right angel.

Circular cone

• A circular cone has base is a circle. The line connecting the center of the base to the vertex is called the axis of the circular cone.

 Right Circular Cone

• In a right circular cone the axis is perpendicular to the base. (If the axis of a circular cone is not perpendicular to the base, it is called an oblique circular cone.) The length of any line segment connecting the vertex to the directrix is called the slant height of the cone.
