Find the arc length of the semicircle

18.8496 units (rounded o1ff to four decimal places)

Step-by-step explanation:

Arc length = 2 × π × r ×

r (radius) = 12 units ÷ 2 = 6 units

Central angle = 180°

For our semicircle, the arc length = 2 × π × 6 × = 18.8495559215 units

Or 18.8496 units (rounded o1ff to four decimal places)

6pi
