How do I solve this? How do I determine the range? Ill they be triple integrals?Please explain to me. Find the volumes in R3. 1. Find the volume U that is bounded by the cylinder surface x^2+y^2=1 and the plane surfaces z=2, x+z=1. 2. Find the volume W that is bounded by the cylindrical surfaces x^2 + y^2 = 1 and x^2 + z^2 = 1. I know these are 2 questions and they're both about finding volumes but the second one seems to have 2 cylinders ??I don't get it.
