How it is worked out

  1. Volume = 4/3 πr³; surface = 4πr².
  2. Volume = 113.097336 and surface area = 113.097336.
Worked examples
InputsAnswer
Radius: 3The sphere has volume 113.097336 cubic units and surface area 113.097336 square units.
Radius: 10The sphere has volume 4,188.790205 cubic units and surface area 1,256.637061 square units.
Radius: 0.5The 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).
