The circumference of a circle can be calculated using the formula C = 2πr, where r is the radius of the circle.
Given that the radius of the circle is 4.5 centimeters, we can plug in this value into the formula:
C = 2π(4.5)
C ≈ 28.26 cm
Therefore, the closest measurement to the circumference of the circle in centimeters is 28.26 cm.
