I know that the volume of a sphere with an exterior radius is of:

V = pie(R^2 - r^2) dH

where R^2 is the exterior surface area and r^2 is the interior surface area. dH is the thickness.

How would I go about finding the thickness? And for R and r, do I simply just plug in the values that are given to me?

Thank you.
