Answer: The arc length of the clock is 31.42cm
Explanation:
1. Use your section formula: S = r (Radius) θ (Theta: Angle in radians)
2. Convert your 180 degrees to radians by multiplying it by π / 180, resulting in π radians.
3. Take your radius of 10cms and multiply it by π, leaving 31.42cm. This is the length of the 180 degree arc.
