Description
What is this formula?
This formula calculates the volume of a spherical cap. A spherical cap is the portion of a sphere cut off by a plane.
When to use it
Use this formula when determining the volume of partially filled spherical tanks, domes, lenses, or cut spherical sections.
Example
If a sphere has a radius of 5 m and the cap height is 2 m:
V = π(2)^2(3×5−2)/3
V ≈ 54.45 m³
