Note: volume is measured in units cubed (e.g. m^3, cm^3, mm^3, etc.).

### Volume of a Sphere

- The
**volume of a sphere**is found using the formula:

V=\frac{4}{3} \pi r^{3}

Where r is the radius.

Example

We wish to find the volume of the above sphere. We do this by first identifying the values we need, in this case we have a radius of 10mm. Now, we substitute this value into our formula to find the volume

V=\frac{4}{3} \pi r^{3}=\frac{4}{3} \pi 10^{3}=4188.79 \mathrm{~mm}^{3}
