To find the diameter of a circle when you have the circumference, you can use the formula:
\[ C = \pi \times d \]
where \( C \) is the circumference and \( d \) is the diameter. We can rearrange this formula to solve for the diameter:
\[ d = \frac{C}{\pi} \]
Given that the circumference \( C \) is 7,459 miles and using \( \pi \approx 3.14 \), we can calculate the diameter:
\[ d = \frac{7,459}{3.14} \approx 2,375.79 \]
So, the diameter of the circle, rounded to the nearest hundredths place, is approximately 2,375.79 miles.
