I have a question, why did you leave the normal vector for the paraboloid a non-unit vector?

[@user-ue5dl1rg9d]

How you took the limits of r and theta . And why theta not 0 to pi

Thank you, very helpful!

How did you write n2 I mean can you please explain

[@ApsiPapsi]

Normal vector to a plane is cross product of 2 vectors in the plane. We can get those 2 vectors by taking the derrivative of the parametrization, since it yields the tangent at a given point. Setting x and y to 0 gives (0,0,1). where we take the negative so our vector points outwards.
