To find the circumference of a circle, you can use the formula:
\[
C = 2 \pi r
\]
where \( r \) is the radius and \( \pi \) is approximately 3.14.
Given that the radius \( r \) is 14 inches, we can substitute this into the formula:
\[
C = 2 \pi \times 14
\]
Calculating this step-by-step:
1. Calculate \( 2 \times 14 = 28 \).
2. Now, multiply by \( \pi \):
\[
C = 28 \pi \approx 28 \times 3.14 = 87.92
\]
Rounding 87.92 to the nearest tenths place gives us 87.9.
Therefore, the circumference of the circle is **87.9 inches**.
