What is the approximate length of the wire she attached to the pendant?

Explanation:

Luz made a semicircular pendant with a radius of 8 centimeters to use on a keychain. She attached a wire around the edge of the pendant. The length of the wire can be calculated using the formula for the circumference of a circle, which is L = 2πr, where r is the radius of the circle.

Given that the radius of the pendant is 8 centimeters, we can find the length of the wire by substituting the value of the radius into the formula:

L = 2 * 3.14 * 8

L = 50.24

Therefore, the length of the wire that Luz attached to the pendant is approximately 50.27 centimeters long.
