Most of us know by now how to find the Volume or Surface Area (pick your poison) of a sphere. But, what do you do when you need to find the radius and are only given the Volume/SA?

Well, sit down and start reading on.

For Volume, take the volume and work backwards, starting with 4 over 3, in which you times by 3 then divide by 4, dive that by pi, and then find the cubed root of that.

Example:

With Surface Area, take the SA, divide that by 4πr^2, then find the square root of that.

Example:

Make sure to round your answers as well.

Ha, “round”, it’s funny because spheres.
