Properties of Sphere
This tool calculates the basic geometric properties of a sphere. Enter the shape dimensions R or D below. The calculated results will have the same units as your input. Please use consistent units for any input.
Surface area =
The sphere is a 3-dimensional object (solid), with all the points of its outer outer surface having an equal distance from a common point, called centre. That distance is called radius of the sphere. The volume of a sphere is given by the formula:
where r the radius.
The outer surface area of the sphere is given by the next formula:
