Question
The constant of proportionality between a circle's diameter, `d`, and its circumference, `C`, is `\pi` (written as pi and pronounced "pie").
In other words, `C=\pi d`.
Common approximations for `\pi` are `3.14`, `\frac{22}{7}`, and `3.14159`. None of these are exactly `\pi`.
Calculate the approximate circumference of a circle with a diameter of `16` centimeters.

To calculate the circumference \( C \) of a circle using the formula \( C = \pi d \), where \( d \) is the diameter, we can use the approximate value of \( \pi \).
Given:
- Diameter \( d = 16 \) centimeters
Using the approximation \( \pi \approx 3.14 \):
\[
C \approx 3.14 \times 16
\]
Calculating this:
\[
C \approx 50.24 \text{ centimeters}
\]
Therefore, the approximate circumference of a circle with a diameter of 16 centimeters is **50.24 centimeters**.
