To find the diameter of a circle from its circumference, you can use the formula:
\[ C = \pi \times d \]
Where \(C\) is the circumference and \(d\) is the diameter. Rearranging the formula to solve for \(d\):
\[ d = \frac{C}{\pi} \]
Given that the circumference \(C\) is 7,459 miles and using \( \pi \approx 3.14\), we can plug in the values:
\[ d = \frac{7459}{3.14} \]
Now calculating \(d\):
\[ d \approx \frac{7459}{3.14} \approx 2374.31 \]
Rounding to the nearest hundredths place, the diameter is:
2,374.31 miles.
