B. 29.3 inches
Arc length = (angle in degrees/360) x 2π x radius
Arc length = (120°/360) x 2π x 14 inches
Arc length = (1/3) x 2π x 14 inches
Arc length = (2/3) x 14π
Arc length = 28/3 x 3.14159
Arc length = 29.3 inches
What is the arc length for an arc that measures 120° if the radius is 14 inches?
A. 263.9 inches
B. 29.3 inches
C. 14.7 inches
