The length of an arc of a circle is given by the formula L = (θ/360) × 2πr, where θ is the central angle in degrees, r is the radius of the circle, and π is approximately equal to 3.14.
Substituting the given values, we get:
L = (128/360) × 2π(12)
L = (0.356) × 2π(12)
L = (0.356) × 24π
L = 8.52π
Rounding to the nearest hundredth, we get:
L ≈ 26.81 feet
Therefore, the answer is (A) 26.81 feet.
