Sphere volume calculator
Calculator
The calculator needs JavaScript. The tables below give the same numbers for common cases.
How it is worked out
- Volume = 4/3 πr³; surface = 4πr².
- Volume = 113.097336 and surface area = 113.097336.
| Inputs | Answer |
|---|---|
| Radius: 3 | The sphere has volume 113.097336 cubic units and surface area 113.097336 square units. |
| Radius: 10 | The sphere has volume 4,188.790205 cubic units and surface area 1,256.637061 square units. |
| Radius: 0.5 | The sphere has volume 0.523599 cubic units and surface area 3.141593 square units. |
How to use it
The volume of a sphere is V = 4⁄3 π r³ and its surface area is 4πr². Doubling the radius multiplies the volume by 8 and the surface area by 4.
For a radius of 3 the volume is about 113.097 and the surface area about 113.097 as well (the two coincide at r = 3).
Frequently asked questions
What is the volume of a sphere with radius 3?
About 113.097 cubic units.
How does volume change when the radius doubles?
It becomes 8 times larger.
How do I find the radius from the volume?
r = (3V ÷ 4π)^(1/3).
