1. Identify knowns:
   • Diameter, d = 10 cm
   • Radius, r = d/2 = 5 cm
   • Central angle, θ = 60°
2. Use the Law of Cosines or the chord length formula:

   \[

   \text{Chord length} = 2r \sin(\theta/2)

   \]

3. Calculate:

   \[

   \text{Chord} = 2 \times 5 \times \sin(30°) = 10 \times 0.5 = 5 \text{ cm}
