# Thread: Intersection of Three cylinders

1. ## Intersection of Three cylinders

Not even a clue where to start other than graphing the shapes.

"Find the volume of the solid enclosed by the cylinders x^2+y^2=4, x^+z^2+1, and y^2+z^2=9"

2. ## Re: Intersection of Three cylinders

I know the volume formula is the triple integral of 1dV, with dV being the restraints, but how do i find the restraints?
