The Properties of a Sector of a Sphere Calculator is used to calculate the volume and surface area of a spherical sector. A spherical sector is a solid of revolution enclosed by two radii from the center of a sphere. (Find out more at

Wolfram Mathworld)
The following equations are used to calculate the sector's volume and surface area:

where:

r is the radius of the sphere

h is the height of the spherical sector (the distance between the points where the two radii intersect the edge of the sphere)

where:

r is the radius of the sphere

h is the height of the spherical sector (the distance between the points where the two radii intersect the edge of the sphere)

s is the diameter of the circular base of the sector.

You may also optionally specify the material the sphere is constructed from to calculate the mass. The mass is
calculated based on the volume of the sector of the sphere and the density of the material. The density of the material is
derived from its specific gravity. Specific Gravities are available for a variety of metals, plastics and woods.

This calculator allows a user to specify English (inches, feet) or Metric (centimeters, meters) as possible units of
measure for the radius and height of the cone. NOTE: All lengths are assumed to
be of the same unit of measurement.
