To find the diameter of a circle given its 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 find the diameter:
\[ d = \frac{C}{\pi} \]
Given that the circumference \( C \) is 7,459 miles and using \( \pi \approx 3.14 \), we can substitute these values into the equation:
\[ d = \frac{7,459}{3.14} \]
Now, performing the division:
\[ d \approx 2,375.1587 \]
Now, rounding this value to the nearest hundredths place gives:
\[ d \approx 2,375.16 \]
Therefore, the diameter of the circle, rounded to the nearest hundredths place, is 2,375.16 miles.
