Answer:

Explanation:
Since we are given the central angle in radians, we should use the following formula for the arc length.

Where s is the arc length, θ is the angle in radians, and r is the radius.
We know this circle has a radius of 9 inches and the central angle is 3.25 radians.
Substitute the values into the formula

Multiply.

The arc length is 29.25 inches.
