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
[tex]\frac{\theta}{360}\times 2\pi r[/tex]
[tex]\frac{\theta}{360}\times circumference[/tex]
[tex]\frac{120}{360}\times 54[/tex]
Hence, option C is correct
