Volume of a Sphere Calculator

How to calculate Volume of sphere calculator?

The volume of a sphere is computed from its radius using a standard geometric formula. Provide the radius and the calculator returns the sphere's volume.

The key formula is V = (4/3) π r^3, where r is the sphere radius.

Using the Volume of sphere calculator calculator: an example

Example values: radius r = 3 cm.

Step-by-step calculation:

• Compute r³: 3³ = 27 cm³.
• Multiply by π: 27 × π ≈ 84.82 cm³.
• Apply the factor 4/3: V = (4/3) × 27 × π = 36 × π ≈ 113.10 cm³.

Frequently Asked Questions

What units will the calculator return?

The result uses cubic units matching the radius unit. For example, if radius is in centimeters the volume is in cm³.

Can I enter the diameter instead of the radius?

Yes. Convert diameter to radius by dividing by two, then enter the radius into the calculator.

Does the calculator use an exact value for π?

The calculator uses the built-in π constant and reports a numeric approximation. For exact symbolic work use the formula with π left as a symbol.

What if I enter zero or a negative radius?

A radius of zero yields a volume of 0. Negative radius values are not physically meaningful; use a non-negative radius.
