Calculation History:

The Conical Frustum Calculator is a tool that helps you calculate the various properties of a conical frustum given any two known variables. It is a simple and easy-to-use tool that can be used by anyone who has basic knowledge of geometry.

Concepts

The concept of calculating the properties of a conical frustum is based on the idea of finding the volume, surface area, slant height, and other properties of a conical frustum. The calculator does this for us automatically.

Formulae

The formulae used by the calculator to calculate the properties of a conical frustum are as follows:

Volume

V = (1/3)πh(r1^2 + r2^2 + r1r2)

where V is the volume of the conical frustum, h is the height of the conical frustum, r1 is the radius of the top base of the conical frustum, and r2 is the radius of the bottom base of the conical frustum.

Surface Area

A = π(r1 + r2)l + πr1^2 + πr2^2

where A is the surface area of the conical frustum, r1 is the radius of the top base of the conical frustum, r2 is the radius of the bottom base of the conical frustum, and l is the slant height of the conical frustum.

Slant Height

l = √((r1 - r2)^2 + h^2)

where l is the slant height of the conical frustum, r1 is the radius of the top base of the conical frustum, r2 is the radius of the bottom base of the conical frustum, and h is the height of the conical frustum.
