Question

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

Answer 1

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

Answer 2

The correct option is C

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

`(\theta)/(360)* 2\pi r`

`(\theta)/(360)* circumference`

`(120)/(360)* 54`

Hence, option C is correct
