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:
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 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.
