spherical crown volume and surface area calculator

radius (r):
height of spherical crown (h):
volume of spherical crown:
surface area of ​​spherical crown:

spherical crown calculation formula:
1. volume of sphere = 4 * π * r3 / 3

2. sphere surface area = 4 * π * r2

3. volume of spherical crown = π * h2 * (3r - h) / 3

4. surface area of ​​spherical crown = 2 * π * r * h
