# Cone – A Phenomenal Figure of Geometry

The cone is one of the most fundamental figures of geometry. It has many unique properties that are not seen in any other figure. It is crucial to study those properties because the cone is a very important figure of geometry.  Basically, the cone is a three-dimensional figure that comprises a sharp projection from a flat base. The extreme point of projection is said to be a vertex or apex. A cone is shaped by a collection of line segments and half-lines that connect the apex to the other distinct points of a base. The axis of a cone is actually a straight line that penetrates the apex and the base possesses circular symmetry. A cone that includes a polygonal base is also known as a pyramid. There are many terminologies related to a cone. It is crucial to study those different terminologies.

The perimeter of the base of the cone is defined as the directrix. The segment that connects the perimeter of the base and vertex is known as generatrix. The base radius is defined as the radius of the cone. The aperture of the cone is the angle between the two generatrixes. If the apex is cut by a plane, then it is referred to as the truncated cone. If the truncation plane is parallel to the base of the cone then it is said to be a frustum. If the base of the cone is elliptical then it is said to be an elliptical cone. It is important to know about the different parameters of the cone-like the surface area of cone, the volume of the cone, and other such factors. These parameters play a crucial role in solving the problems associated with the cone. This article discusses the various parameters of the cone.

## The major fundamentals of cone:

• Area of cone: To calculate the area of the surface it is important to calculate the slant height of the cone first. The slant height is calculated by obtaining the value of under the root of the square of the radius and the height of the cone. After calculating the slant height, one can easily calculate the area of the surface by obtaining the product of pie and the radius and slant height respectively. The area of the circular base can be obtained by the product of pie and the square of the radius.
• The volume of the cone: The volume of the cone is computed by obtaining the product of pie, the square of the radius, and the height of the cone. When this product is divided by three, the volume of the cone is obtained. It is crucial to practice a variety of problems based on the volume of the cone. The formula can be memorized by rigorous practice. Questions on the volume of the cone are asked in many important examinations.
• Centre of Mass: The center of mass of a solid cone that has uniform density lies one-fourth of the way from the center of the base to the apex on the straight line that connects the two. It is very important to practice problems on this concept too. Questions regarding the center of mass are asked in Physics.
• Importance of cone in geometry: The cone plays a vital role in geometry. It is one of the most well-known figures of geometry and is also used extensively in projective geometry.

This article is an attempt to cover the important concepts of the cone. It is crucial to practice the fundamentals of this figure as well as those of other figures. The sphere is another important figure. One should be well-acquainted with the parameters of the sphere such as the volume and surface area of sphere.
