Final answer:
The circumference of a circle with a diameter of 24 millimeters is approximately 75.36 millimeters.
Step-by-step explanation:
The diameter of a circle is the distance across the circle through its center. To find the circumference of a circle, you can use the formula C = πd, where C represents the circumference and d represents the diameter of the circle. In this case, the diameter of the circle is 24 millimeters. So, the circumference of the circle can be found by multiplying 24 by π (approximately 3.14).
C = 3.14 × 24 = 75.36 millimeters
After rounding to the nearest hundredth, the circumference of the circle is approximately 75.36 millimeters.
