Question

the circumference of the circle shown below is 54 centimeters. which expression gives the length in centimeters of XY?​

Answer 1

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

Answer 2

The correct answer is option C. (120)/(360)*54
