Answer 1

To calculate the circumference of Earth using its diameter, you can use the formula:

\[
\text{Circumference} = \pi \times \text{Diameter}
\]

Given the diameter of Earth is 7,918 miles, we can substitute that into the formula:

\[
\text{Circumference} = \pi \times 7,918 \text{ mi}
\]

Using the approximate value of \(\pi \approx 3.14\):

\[
\text{Circumference} \approx 3.14 \times 7,918 \approx 24,835.32 \text{ mi}
\]

Rounding this to the nearest mile gives us approximately:

\[
24,835 \text{ mi}
\]

However, if we compare it to the provided choices, the closest option is:

**24,875 mi.**

So, the circumference of Earth to the nearest mile is **24,875 mi.**
