Answer:
The correct answer is A) 450 cm
Step-by-step explanation:
In order to do this, we need to first find the ratio of the angle to the circle as a whole. A whole circle is 360 degrees and then we divide by the share, which is 12 degrees.
360/12 = 30
Now that we know this is a factor of 30, we can multiply the arc length by that much.
15cm * 30 = 450cm
