The circumference of a circle can be calculated using the formula:
Circumference = 2 * radius * π
Substitute the radius given (4.5 cm) into the formula:
Circumference = 2 * 4.5 cm * π
Circumference = 9 cm * π
To find an approximate decimal value for π, you can use 3.14.
Circumference ≈ 9 cm * 3.14
Circumference ≈ 28.26 cm
Therefore, the closest measurement to the circumference of the circle in centimeters is 28.26 cm.
