To calculate the circumference \( C \) of a circle, you can use the formula:
\[
C = 2\pi r
\]
where \( r \) is the radius of the circle.
Given that the radius \( r \) is 4.5 cm, we can substitute this value into the formula:
\[
C = 2\pi(4.5)
\]
Calculating this gives:
\[
C = 9\pi \approx 9 \times 3.14 \approx 28.26 \text{ cm}
\]
Thus, the measurement closest to the circumference of the circle is **28.26 cm**.
