To calculate the circumference of a circle (in this case, the tire rim), you can use the formula:
\[
\text{Circumference} = \pi \times \text{diameter}
\]
Given that the diameter of the tire rim is 15 inches and using 3.14 for \(\pi\):
\[
\text{Circumference} = 3.14 \times 15
\]
Calculating this:
\[
\text{Circumference} = 47.1 \, \text{inches}
\]
Therefore, the circumference of the tire rim is **47.1 in.**
\[
\text{Circumference} = \pi \times \text{diameter}
