Find the flux (calculus problem)?

The directions for this calculus problem say find the flux of F across surface S (that is find the double integral F (ds)) where F = (x,2y,z), S is the part of the cone (x^2+z^2)^1/2=y inside of the cylinder x^2+z^2=1 and n points to the right. I have tried many times to get this, but can't get it to work. I'd appreciate if someone could give me the answer, along with the steps in which they got there. Thanks!
