To find the arc length of \( AB \) in the given circle, we can follow these steps:

### Step 1: Identify the Given Values
- **Radius**: \( r = 8 \) feet.
- **Central Angle**: \( \theta = 45^\circ \).

### Step 2: Use the Formula for Arc Length
The formula for the length of an arc is given by:

\[
\text{Arc Length} = \frac{\theta}{360^\circ} \times 2\pi r
\]

where:
- \( \theta \) is the central angle in degrees.
- \( r \) is the radius.
- \( 2\pi r \) is the circumference of the circle.

### Step 3: Plug in the Values
\[
\text{Arc Length} = \frac{45}{360} \times 2\pi \times 8
\]

### Step 4: Simplify the Expression
Let's calculate the value of the arc length:

\[
\text{Arc Length} = \frac{1}{8} \times 2\pi \times 8 = \pi \approx 3.14 \, \text{feet}
\]

Rounding to the nearest hundredth, the arc length of \( AB \) is approximately **3.14 feet**.
