Answer:

\theta=1.72  radians

Step-by-step explanation:

Arc length and radius is given. So, we need to know the arc length formula for a circle.

That is:

s=r\theta

Where s is the arc length

r is the radius

\theta  is the angle (IN RADIANS)

We have:

s = 15.5

r = 9

Now, we substitute and find the angle:

s=r\theta\\15.5=9\theta\\\theta=\frac{15.5}{9}\\\theta=1.72

The angle, in radians, in 1.72
