Final answer:

The circumference of a circle with a diameter of 16.5 units is approximately 51.84 units, calculated using the formula C = πd.

Step-by-step explanation:

To calculate the circumference when the diameter is known, you can use the formula C = πd, where C is the circumference and d is the diameter. Using π approximately equal to 3.14159, if the diameter is 16.5, the circumference would be:

C = 3.14159 × 16.5 = 51.83685

So, the circumference of a circle with a diameter of 16.5 units is approximately 51.84 units.

If we reference a similar problem, such as calculating Earth's circumference given its diameter of 12,740 km, we would follow the same formula, multiplying the diameter by π to find the circumference. Another related mathematical concept is fitting a circle inside a square where the circle's diameter is equal to the side length of the square. Specifically, a = 2r, indicating that the diameter is twice the radius.
