Question
![**Problem Statement:**
Find the area of the surface given by \( z = f(x, y) \) that lies above the region \( R \).
**Given Function:**
\[ f(x, y) = 4 + x^2 - y^2 \]
**Region \( R \):**
\[ R = \{ (x, y) : x^2 + y^2 \leq 9 \} \]
**Explanation:**
- The surface is defined by the function \( f(x, y) \).
- The region \( R \) is a circle centered at the origin with radius 3 (since \( 9 = 3^2 \)).
**Graphical Representation:**
- A circular region on the xy-plane with radius 3, centered at the origin.
- The function f(x, y) describes a paraboloid that extends above the circle.
**Objective:**
Calculate the area of this surface above the defined circular region.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbf01af3a-a116-4425-8c3e-5f354c5ced3a%2F38c7bbe8-dc96-4fe8-b6cd-d00dfbb992e9%2Fzvnzblh_processed.png&w=3840&q=75)
