Question: 1 / 465

If a circle has a diameter of 8, what is its circumference?

6.28

12.56

25.13

To determine the circumference of a circle, you can use the formula:

Circumference = π × diameter.

In this case, the diameter of the circle is given as 8. Therefore, the circumference can be calculated as follows:

Circumference = π × 8.

Using 3.14 as an approximation for π:

Circumference ≈ 3.14 × 8 = 25.12.

For a more precise value, if you use 3.14159 for π, the calculation would yield approximately 25.13, which rounds closely to 25.13.

This means that the circumference of the circle is indeed about 25.13, which aligns with the correct option of C. This is the reason why this choice is valid for the question posed, as it accurately represents the computed value based on the diameter provided.
