What is the circumference of a circle with a diameter of 8?

To determine the circumference of a circle, the formula used is C = πd, where C represents the circumference and d represents the diameter. In this case, the diameter given is 8.

Plugging in the value:

C = π × 8.

Using the value of π as approximately 3.14 for calculation:

C = 3.14 × 8 = 25.12, which can be rounded to 25.13.

Therefore, the correct circumference of the circle, given a diameter of 8, is 25.13, which aligns with one of the choices provided. This value accurately reflects the relationship between the diameter and the circumference, showcasing the importance of using the proper formula.
