Answer:

C ≈ 11.71 cm

Step-by-step explanation:

using the ratio arc AC : circumference C = angle at centre of sector : 360°

$\frac{AC}{C}$ = $\frac{123}{360}$ , that is

$\frac{4}{C}$ = $\frac{123}{360}$ ( cross- multiply )

123 × C = 4 × 360 = 1440 ( divide both sides by 123 )

C = $\frac{1440}{123}$ ≈ 11.71 cm ( to the nearest hundredth )
