g100num [7]

Answer:

The correct option is C

Step-by-step explanation:

Given the circumference of circle which is 54 cm and also the measure of arc XY is 120°

we have to find the expression for arc length of XY

The arc length can be calculated by the formula

\frac{\theta}{360}\times 2\pi r

\frac{\theta}{360}\times circumference

\frac{120}{360}\times 54

Hence, option C is correct
