The Volume of a Sphere calculator computes the volume of a sphere (V) based on the radius of the sphere (r).
INSTRUCTIONS: Choose units and enter the following:
Sphere Volume (V): The Volume of the Sphere (v) is returned in cubic meters. However, this can be automatically converted to numerous other volume units (e.g. cubic feet, gallons and barrels) via the pull-down menu.
The formula for the volume of a sphere is:
V = 4/3•π•r³
The equation for the volume of a sphere is as follows:
The volume of a sphere is a special case of the Volume of an Ellipsoid (CLICK HERE) where the three semi-axes (a, b, c) are all the same and equal to the radius (r)
One can see that they are algebraically the same.
Volume is a three dimensional measurement of the amount of space taken up by an object. Volume units are cubic measurements for solid objects such as cubic inches and cubic meters. Fluid objects have separate units such as fluid ounces, gallons, barrel and liters.
The volume of an object can measured by the liquid it displaces or be calculated by measuring its dimensions and applying those dimensions to a formula describing its shape. Many such calculations are available in the following list of calculators.
In many cases, the calculators are for a column with a geometric shaped base and vertical sides. The most basic form is an Area times a Height.
