**Finding Arc Length**

In Exercises 97-100, find the length of the arc on a circle of radius [tex]r[/tex] intercepted by a central angle [tex]\theta[/tex].

| Exercise | Radius [tex]r[/tex] | Central Angle [tex]\theta[/tex] |
|----------|------------------------|---------------------------------|
| 97. | 14 inches | [tex]\pi[/tex] radians |
| 98. | 9 feet | |
| 99. | 27 meters | |
| 100. | 12 centimeters | |

(Note: Ensure that each exercise has a specified central angle [tex]\theta[/tex] to complete the calculation for arc length.)

Answer :

To find the length of an arc on a circle intercepted by a central angle, you can use the formula for arc length, which is:

[tex]\[ \text{Arc Length} = r \times \theta \][/tex]

where:
- [tex]\( r \)[/tex] is the radius of the circle,
- [tex]\( \theta \)[/tex] is the central angle in radians.

For Exercise 97, we're given:
- Radius [tex]\( r = 14 \)[/tex] inches,
- Central angle [tex]\( \theta = \pi \)[/tex] radians.

Let's calculate the arc length step by step:

1. Identify the values:
- Radius [tex]\( r = 14 \)[/tex] inches.
- Central angle [tex]\( \theta = \pi \)[/tex] radians.

2. Apply the formula:
[tex]\[
\text{Arc Length} = 14 \times \pi
\][/tex]

3. Calculate the arc length:
- Multiply the radius by the central angle.
- This results in an arc length of approximately [tex]\( 43.98 \)[/tex] inches.

So, the length of the arc is approximately [tex]\( 43.98 \)[/tex] inches.
