For each of the following solids identify the picture and the iterative integral of a function f(x,y,x) with a brief explanation:

1) E is the solid bounded by the surfaces x^2 + y^2 =1, z=0, x+z=2.

2) E is the solid bounded by the surfaces x+y+z=1, x=0, y=0, z=0.

3) E is the solid bounded by the surfaces x=1, x^2 – y^2 – z^2 = 0.

4) E is the solid bounded by the surfaces x=0, y=0, z=0, x^2 + y^2 + z^2 =1.
