Heres the question:

What mass of a material w/ density p is required to make a hollow spherical shell having inner radius r1 and outer radius r2?

I understand everything besides the inner and outer radius part. What is the textbook trying to say with that statement. How do you know to subtract them? So if you understood to subtract the radii can you please explain your thought process?

Again thanks a alot.
