Expert Solution
Step 1

The objective is to evaluate EezdV, where E is enclosed by the paraboloid z=5+x2+y2, the cylinder x2+y2=1, and the xy plane.

Let, x=rcosθ, y=rsinθ, z=z then dzdydx=rdrdθ

Limits of z are, z=0 to z=5+r2

Limits of r are, r=0 to r=1

Limits of θ are, θ=0 to θ=2π

Then EezdV=θ=02πr=01z=05+r2ezrdzdrdθ
