Leo designs a piece of jewelry in the shape of a regular pentagon. Each side of the object measures 3 centimeters. Leo photographs the object, enlarges it so that the sides each measure 8 centimeters, and prints the photo. What scale factor did Leo use to create the photograph from the original?(1 point)

To determine the scale factor that Leo used to create the photograph from the original pentagon, we can use the formula:

\[ \text{Scale Factor} = \frac{\text{New Size}}{\text{Original Size}} \]

In this case, the original side length of the pentagon is 3 centimeters, and the new side length after enlargement is 8 centimeters. Plugging these values into the formula gives:

\[ \text{Scale Factor} = \frac{8 \text{ cm}}{3 \text{ cm}} = \frac{8}{3} \]

Therefore, the scale factor used by Leo to enlarge the photograph is:

\[ \frac{8}{3} \]

Looking at the provided responses, the correct answer is:

\(\frac{8}{3}\)
