A circle has a radius of 4.5 centimeters. Which measurement is closest to the circumference of the circle in centimeters?
Question 3 options:
14.13 cm
28.26 cm
63.59 cm
56.52 cm
The circumference of a circle is given by the formula:
Circumference = 2 * π * radius
Substituting the given radius of 4.5 centimeters:
Circumference = 2 * π * 4.5
Using an approximation of π as 3.14159:
Circumference ≈ 2 * 3.14159 * 4.5
Circumference ≈ 28.27 cm
The measurement closest to the circumference of the circle in centimeters is 28.26 cm.
