To find the circumference of a circle, you can use the formula:
\[ C = \pi \times d \]
where \( C \) is the circumference and \( d \) is the diameter. Given that the diameter \( d \) is 15.4 inches, we can calculate the circumference:
\[ C = \pi \times 15.4 \]
Using the approximation \( \pi \approx 3.14 \):
\[ C \approx 3.14 \times 15.4 \approx 48.036 \]
Now, rounding this to the tenths place, we get:
\[ C \approx 48.0 \]
Therefore, the circumference of the cricket is approximately 48.0 inches.
