Find the area of the part of the paraboloid z = 9 - x^2 - y^2 that lies above the xy-plane.

Parameterize this surface (call it ) by

with and . Take the normal vector to to be

Then the area of is

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
