Final answer:
The angle in radians is approximately 2.022.
Step-by-step explanation:
To find the angle in radians, we can use the formula:
angle = arc length / radius
In this case, the arc length is 18.2 and the radius is 9. Plugging in these values, we get:
angle = 18.2 / 9 = 2.022
So, the angle in radians is approximately 2.022.
