Spherical Cap Calculator

Connected geometry workflow

v10.86 connects broad area, perimeter, volume and surface-area heads with triangle, circle, polygon, coordinate-center and similarity specialists without replacing the established geometry engines.

Use consistent measurements and valid geometric assumptions

Keep linear inputs in a consistent unit, verify that side lengths or coordinate points can form the stated shape, and treat sketches as explanatory unless explicitly marked to scale. Coordinate formulas can become unstable for nearly degenerate shapes, so invalid or nearly collinear inputs are rejected rather than silently returning misleading values.

How to use this Spherical Cap Calculator

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

1. Enter, paste, upload, or choose the inputs shown in the tool above.
2. Adjust the available options for the result you need.
3. Review the output before copying, downloading, or using it elsewhere.

What this tool does

Enter sphere radius and cap height to solve the cap geometry with the valid 0 < h ≤ 2R domain shown explicitly.

Practical tips and limits

Review the inputs and result before using the output elsewhere. Keep the original data when the operation changes or replaces content.
