Understanding the Calculation

The volume of a conical frustum (truncated cone) is calculated using the formula:

  • Volume = (π * h * (r1² + r1 * r2 + r2²)) / 3

Here, r1 and r2 are the top and bottom radii, respectively, and h is the height. This formula derives from the integral calculus method of finding the volume of a solid of revolution.
