The **Surface Area of a Spherical Cap** calculator returns the surface area based on the radius of the sphere and the height of the cap.

**INSTRUCTION:** Choose units and enter the following:

- (
**r**) Radius of the Sphere - (
**h**) Height of the Sphere Cap

**Surface Area of Sphere Cap (SA):** The surface area is returned in square meters. However this can be automatically converted to compatible units via the pull-down menu.

The formula for the surface area of a sphere cap is:

where:

- SA = Sphere Cap Surface Area
- r = radius of the sphere
- h = height of the sphere cap

The formula provides the lateral area (surface area) of the cap of a sphere. The cap is defined by the depth (**h**) from the surface and the radius (**r**) of the sphere. The cap is formed of a plane perpendicular to the radius which cuts off the cap of the sphere at a distance (h) from the outside of the sphere.
