## What is Conical Frustum?

A conical frustum, simply called a frustum, is a three-dimensional geometric shape that results from cutting a cone with a plane parallel to its base. In other words, it’s a portion of a cone that is removed by slicing it horizontally (or parallel to the base) at a certain height. The resulting shape has two circular bases of different sizes and a curved lateral surface connecting them.

Key characteristics of a conical frustum include:

**Two Circular Bases:**A conical frustum has two circular bases, one larger (the lower base) and one smaller (the upper base).**Parallel Bases:**The bases are parallel to each other, which means that the distance between them is consistent along the entire height of the frustum.**Curved Lateral Surface:**The lateral surface of the frustum is curved and connects the two circular bases.**Height:**The height of the frustum is the perpendicular distance between the two bases.

## All Formulae Related to Conical Frustum

**Volume of a Conical Frustum (V):**- The volume of a conical frustum is calculated using the formula:
- V = (1/3) * π * h * (R^2 + r^2 + R * r)

- V is the volume of the frustum.
- π (pi) is approximately 3.14159.
- h is the height of the frustum.
- R is the radius of the lower (larger) base.
- r is the radius of the upper (smaller) base.

**Surface Area of a Conical Frustum (A):**- The total surface area of a conical frustum includes both the lateral surface area and the areas of the two circular bases. It is calculated using the formula:
- A = π * (R + r) * l + π * R^2 + π * r^2

- A is the total surface area of the frustum.
- π (pi) is approximately 3.14159.
- R is the radius of the lower (larger) base.
- r is the radius of the upper (smaller) base.
- l is the slant height of the frustum, which can be calculated using the Pythagorean theorem: l = √(h^2 + (R – r)^2)

**Lateral Surface Area of a Conical Frustum (Al):**- The lateral surface area is the area of the curved surface of the frustum and is calculated using the formula:
- Al = π * (R + r) * l

- Al is the lateral surface area of the frustum.
- π (pi) is approximately 3.14159.
- R is the radius of the lower (larger) base.
- r is the radius of the upper (smaller) base.
- l is the slant height of the frustum.
