Online calculator for crown volume and surface area

radius(r)：
The height of the ball crown (h)：
The volume of the ball crown：
Crown surface area：

Crown calculation formula：

1. Ball volume= 4 * π * r3 / 3

2. Ball surface area = 4 * π * r2

3. Crown volume = π * h2 * (3r - h) / 3

4. Crown surface area = 2 * π * r * h
