In order to find the length of a circle, recall the formula for finding the length of a circle. The formula looks like this: L = 2 * pi * r. Where pi is a constant number equal to 3 (rounded to integers), r is the radius of the circle. We substitute the decimal fraction of 2.5 centimeters into the formula instead of the radius and find the length of this circle. We get: L = 2 * pi * r = 2 * pi * 2.5 = 5 * 3 = 15 centimeters.
Answer: 15 centimeters.
