Slant Height of a Cone

A slant height of the cone is measured along its curved surface which is also the longest height of the cone. It is the line segment that connects the tip of the cone (vertex) to a point on the boundary of its base. It is generally measured in units such as centimeters (cm) and meters (m).

Formula for Slant Height of a Cone

Formula for calculating the slant height of the cone can be derived by using the Pythagorean theorem. It can be defined as:

l = √h2 + r2

where,

  • l is Slant Height of Cone
  • h is Altitude(height) of tCone
  • r is Radius of Base

What is a Cone?

Cone is a three-dimensional Geometric Figure that has a flat and curved surface called a base along with a pointed tip known as a vertex or apex. It is one of the most common figures studied in geometry.

In this article, we will learn about what is a cone, the parts of a cone, the number of faces, edges, and Vertices in a cone, cone formulas, and many more concepts related to Cones in detail.

What is a Cone?

Cone is a 3-D figure whose one of the portions is circular and flat and the other portion is pointed. Cone in math is one of the most commonly used figures. It appears to be a combined version of two 2-D figures namely a triangle and a circle. We can also say that Cone is a stack of many rings with a decreasing radius. The most common examples of cones are an ice cream cone, a sharpened pencil lead, a birthday cap, and the list goes on. Even our eyes have 6–7 million cone cells which help them adjust to color sensitivity....

Surface Area of Cone

In solid shapes, a surface area can be defined as the total area covered by all its faces(i.e. flat as well as curved). In a cone, a surface area is the sum total of the area of its flat surface and the curved surface. It is the area that covers the outer surface of the cone. It is measured in square units like m2,cm2 etc....

Volume of a Cone

Cone being a 3-D shape occupies space and thus has a volume which can be described as the amount of space it occupies or in simple words it can be said to be the capacity of the cone. It is measured in cubic units like m3, cm3, in3 etc....

Frustum of a Cone

The term “frustum” is a Latin word meaning ‘a piece’. If we take a cone and slice it into two parts (cut parallel to the base). The upper part of the cone will maintain its shape (i.e. a cone) and the lower part will be the frustum. In other words, the frustum can be said to be the flat-top cone (i.e. a cone whose upper part is flattened). Some common facts about the Frustum of a Cone:...
