Spherical Cap Volume Calculator

    Calculate spherical cap volume, curved surface area, base radius, and total area from sphere radius, cap height, or base radius.

    The calculator uses sphere radius, cap height, and the circular base radius to estimate volume and surface areas.

    Spherical cap volume

    English SERP language favors spherical cap for a one-plane slice of a sphere. The calculator therefore uses sphere radius, cap height, and base radius rather than a literal translation of the Russian spherical segment wording.

    R is the sphere radius and h is the cap height.

    a is the base radius of the circular cut.
