Calculating Copper Volume for Hollow Spherical Shell

[babysnatcher]

How many grams of copper are required to make a hollow spherical shell having an inner radius of 5.70 cm and an outer radius of 5.75 cm? The density of copper is 8.92 g/cm^3.

Ok, so, how do I find the height? Or solve the problem without the height?

It's a hollow sphere, and you are given the inner and outer radii.

What height are you talking about?

Height?

It's a sphere. It's symmetric. If you are given a radius, that gives you the distance from centre to edge in ANY direction.

Do you know the equation for the volume of a sphere? (I edited this post)

Oh, my bad xD! When I saw shell, I immediately thought cylinder.
