To find the circumference of a circle, you can use the formula:
\[
C = \pi d
\]
where \( C \) is the circumference and \( d \) is the diameter of the circle.
Given that the diameter \( d \) is 18 inches and using \( \pi \approx 3.14 \):
\[
C = 3.14 \times 18
\]
Calculating this gives:
\[
C = 56.52 \text{ inches}
\]
So, the circle's circumference is approximately 56.52 inches when rounded to the nearest hundredth.
