Sphere Volume Calculator
Calculate the volume of any sphere instantly using its radius or diameter.
How to Calculate the Volume of a Sphere
A sphere is a perfectly round geometrical object in three-dimensional space. The volume represents the total space inside the sphere.
Volume of a Sphere
V = (4/3)πr³Where r is the radius
Using Diameter
V = (1/6)πd³Where d is the diameter (d = 2r)
Examples
Radius of 3 units
1r = 3
2V = (4/3)π(3³)
3V = (4/3)π(27)
4V = 36π ≈ 113.1
Frequently Asked Questions
Can I find volume with diameter?
Yes! Just divide the diameter by 2 to get the radius, or use V = (1/6)πd³.
What is the formula?
The formula for volume of a sphere is V = (4/3)πr³.
