Evaluate ∫∫s z ds, where s is the surface whose sides s1 are given by the cylinder x2 + y2 = 81, whose bottom s2 is the disk x2 + y2 ≤ 81 in the plane z = 0, and whose top s3 is the part of the plane z = 9 + x that lies above s2.

Someone this is due ! > .< create an equation that can be used to find the value of x? hint: what type of angle pair do you see? here are the questions to answer, after you create an equation: 1) what should be the total amount used for this type of angle pair? explain how you know. 2) what is the answer to your equation for "x"? 3) after you find your answer for "x" in your equation, find the degree measurement for angle aed?
