Cone is a three-dimensional shape in geometry that narrows smoothly from a flat base to a point called the apex or vertex. Learn cone types and concept in detail.

A cone is a shape created by connecting the points on a circular base to a common point, known as the apex or vertex, using a series of line segments or lines (which does not contain the apex). The height of the cone is determined by measuring the distance between its vertex and base. The radius of the circular base is also considered.

A right cone is a cone with its vertex above the center of the base. It is also called right circular cone. You can easily find out the volume of a cone if you have the measurements of its height and radius and put it into a formula. Therefore, the volume of a cone formula is given as. The volume of a cone = (1/3) πr 2 h cubic units. Where,

The curved surface of a cone is the area of the cone excluding the base. In other words, it is the area of the cone when it is unfolded as shown in the above figure as an unrolled lateral area. The formula to calculate the curved surface area of a cone is given by: Curved Surface Area (CSA) = πrl. Here, r = Radius of the circular base of the cone

Frustum of cone is the part of cone when it is cut by a plane into two parts. The upper part of cone remains same in shape but the bottom part makes a frustum. To get this part of the right circular cone we have to slice it horizontally or parallel to the base. Both pieces have different volumes and areas. Learn Volume Of Cone here.

The radius of the circular base is considered as the radius of the cone itself. The height, slant height and radius of the cone are denoted by ‘h’, ‘l’ and ‘r’, respectively. In our daily life, we come across a number of objects that are in the shape of a cone, for instance, birthday hats, ice-cream cones, and rocket heads.

Cone is a three-dimensional structure having a circular base where a set of line segments, connect all of the points on the base to a common point called apex. A cone can be seen as a set of non-congruent circular discs that are stacked on one another such that ratio of the radius of adjacent discs remains constant.

A cone is a solid which has a circular base and narrows smoothly from the surface to the top at a point called apex or vertex. Example: An icecream cone: Cylinder: A cylinder is a 3d solid shape that has two parallel circular bases connected by a curved surface. It has no vertex. Example: Gas cylinder: Sphere

The only difference between 2D shape and 3D shapes is that 2D shapes do not have a thickness or depth. Usually, 3D shapes are obtained from the rotation of the 2D shapes. The faces of the solid shapes are the 2D shapes. Some examples of the 3D shapes are a cube, cuboid, cone, cylinder, sphere, prism and so on. Types of 3D Shapes

The lower part of a cone when it is sliced about the axis parallel to its base, is called the frustum of a cone. Give some real life examples where the objects have conical shapes. A Christmas tree, ice cream cones, party hats, funnels, and traffic cones are a few common examples of cone shaped objects.
