Answer:
Step-by-step explanation:
Since we are given the central angle in radians, we should use the following formula for the arc length.
Where <em>s</em> is the arc length, θ is the angle in radians, and <em>r</em> is the radius.
We know this circle has a radius of 9 inches and the central angle is 3.25 radians.
- θ= 3.25
- r= 9 in
Substitute the values into the formula
Multiply.
The arc length is <u>29.25 inches. </u>
