How does the Spherical Cap Calculator work?

Volume = (πh²/3) × (3r - h) where h = cap height, r = sphere radius Then: Surface area (curved) = 2πrh Then: Full sphere cap (h = 2r) gives 4πr² (full sphere surface) Then: Constraint: 0 < h ≤ 2r.

Can you give an example of how to use the Spherical Cap Calculator?

Example: Input r=10, h=3 gives a result of Vol 282.7.

Is the Spherical Cap Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.
