**Problem: Surface Area of Revolution**

Find the exact area of the surface obtained by rotating the curve about the x-axis.

**Function:**
\[ y = \sqrt{5 - x} \]
for the interval \[ 3 \leq x \leq 5 \]

**Graph Description:**

The graph displays the curve \( y = \sqrt{5 - x} \) within the specified domain. The curve is plotted on a Cartesian plane with the x-axis ranging from approximately -1 to 6 and the y-axis ranging from -2 to 2. 

- The curve starts at the point (3, 1.414) since \( y = \sqrt{5 - 3} = \sqrt{2} \).
- It ends at the point (5, 0), where \( y = \sqrt{5 - 5} = 0 \).
- The curve represents a downward slope, concave downward as it approaches the x-axis at x = 5.

The task is to determine the surface area generated when this segment of the curve is revolved around the x-axis.
