An arc of length 8 in. is intersected by a central angle in a circle with a radius of 3 in. What is the measure of the angle? Round your answer to the nearest tenth.

Use the arc-length formula s = rθ, where θ is measured in radians. Solving gives θ = s/r = 8/3 ≈ 2.67 radians, which rounds to 2.7 radians. Therefore, the correct choice is C, 2.7 radians.
