To calculate the circumference of the Earth using its diameter, you can use the formula for circumference:
\[
C = \pi \times d
\]
where \( C \) is the circumference and \( d \) is the diameter. Given that the diameter of the Earth is 7,918 miles, we can substitute the value into the formula:
\[
C \approx 3.14 \times 7,918
\]
Calculating this gives:
\[
C \approx 24,878.32 \text{ miles}
\]
Rounding to the nearest mile, the circumference of Earth is approximately 24,875 miles.
So the correct response is:
**24,875 mi.**
\[
C = \pi \times d
\]
