What is the measure of central angle AOB to the nearest tenth of a degree?

An image shows a circle with central angle A O B. O is at the center of the circle. Points A and B are on the circumference of the circle making A O and B O radii of the circle. A B is an arc along the circumference of the circle and is labeled showing the arc length of A B is 9 centimeters. A O is labeled 5 centimeters.

The measure of <AOB
is approximately blank degrees.

Arc length s = rθ (θ in radians). So θ = s/r = 9/5 = 1.8 radians.
Convert to degrees: θ° = 1.8 × 180/π ≈ 1.8 × 57.2958 ≈ 103.1324°.
Rounded to the nearest tenth: 103.1°.
