To calculate the circumference of a circle, we can use the formula:

$C = \pi \times d$

Where:

• $C$ is the circumference,
• $\pi$ is approximately $3.14$,
• $d$ is the diameter of the circle.

Given that the diameter $d = 6$ inches, we can substitute the values into the formula:

$C = 3.14 \times 6 = 18.84$

So, the circumference of the circle is 18.84 inches (rounded to the nearest hundredth).

Tip: Always remember that $\pi$ is a non-terminating, non-repeating decimal, but using a rounded value like $3.14$ is sufficient for most practical purposes.
