To find the circumference of the Earth, we can use the formula for the circumference of a circle:
\[ C = \pi \times D \]
where \( C \) is the circumference and \( D \) is the diameter. Given that the diameter of the Earth is 7,918 miles, we can plug that value in:
\[ C \approx 3.14159 \times 7,918 \]
Calculating this:
\[ C \approx 3.14159 \times 7,918 \approx 24,869.5 \text{ miles} \]
Rounding to the nearest mile, we find:
\[ C \approx 24,870 \text{ miles} \]
However, the closest option given is:
**24,875 mi.**
So, the correct answer is **24,875 mi.**
