1. The problem statement, all variables and given/known data A cylindrical hole of radius R is drilled through the center of a sphere of radius 3. Use the method of cylindrical shells to find the volume of the remaining solid, given that the solid is 6 cm. high. 2. Relevant equations V= ∫2* ∏rh dr (shell method) 3. The attempt at a solution I think this is the form to be used for this problem, but I am probably mistaken. 2 * ∫2* ∏ * x (R^2 - x^2) dx with a= r and b= R 4∏ ∫x (R^2 - x^2) dx Then I'm stumped on how to do this :/ Thank you for your help.
