To calculate the circumference of a circle, you can use the formula:
\[ C = 2 \pi r \]
where \( C \) is the circumference and \( r \) is the radius.
Given that the radius \( r \) is 14 inches, we can substitute this value into the formula:
\[ C = 2 \pi (14) \]
\[ C = 28 \pi \]
Now, using the approximate value of \( \pi \approx 3.14 \):
\[ C \approx 28 \times 3.14 \]
\[ C \approx 87.92 \]
Rounding this to the nearest tenths place:
The circumference is approximately **87.9 inches**.
