The length of a circular arc is determined by the formula: L = π * θ, where θ is the central angle in radians or L = π * r * α / 180, where r is the radius, α is the central angle in degrees.
L = π * r * α / 180 = π * 12 * 100/180 = π * 12 * 10/18 = π * 120/18 = π * 20/3 cm, which is approximately 20.94 cm.
