Volume of a sphere formula A sphere is a perfectly round geometrical 3D object. The formula for its volume equals: volume = (4/3) × π × r³ Usually, you don't know the radius — but you can measure the circumference of the sphere instead, e.g., using the string or rope.
Calculate the surface areas, circumferences, volumes and radii of a sphere with any one known variables. Online calculators and formulas for a sphere and other geometry problems.
The volume of a sphere is how much space is inside it, and calculating this volume is easy! All you need to do is find the sphere’s radius, then plug it into a simple formula, V = ⁴⁄₃πr³.
Use this spherevolume calculator to easily calculate the volume of a sphere, given its radius in any metric: mm, cm, meters, km, inches, feet, yards, miles, etc.
Now, finding the volume of a sphere is easy. In order to calculate the volume of the sphere, all we need is its radius. Even if the radius is not given but just the diameter, we can still find the volume. Since the diameter is twice the radius, we can simply divide the diameter by [latex]2 [/latex] to get the radius.
Here you will learn about the volume of a sphere, including how to calculate the volume of a sphere given its radius and how to find the volume of a hemi-sphere.
The volume of sphere is the space occupied by the sphere in 3-D plane. It is given by the formula 4/3 πr^3. Learn its Definition, Formula, and Derivation along with its Surface Area solved examples, and FAQs.
