The circumference of a circle can be calculated using the formula:
\[ C = \pi \times d \]
where \( C \) is the circumference and \( d \) is the diameter.
Given the diameter of Earth is 7,918 miles, we can substitute this into the formula:
\[ C = \pi \times 7,918 \]
Using the approximate value of \(\pi \approx 3.14159\):
\[ C \approx 3.14159 \times 7,918 \approx 24,875.7 \]
Rounding to the nearest mile, the circumference of Earth is approximately 24,876 miles.
Thus, the closest option from the given responses is:
**24,875 mi**
\[ C = \pi \times d \]
where \( C \) is the circumference and \( d \) is the diameter.
