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 the diameter:
\[
d = \frac{C}{\pi}
\]
Given that the circumference \(C\) is 7,459 miles and using \(\pi \approx 3.14\):
\[
d = \frac{7,459}{3.14}
\]
Calculating this:
\[
d \approx 2,376.06
\]
So, the diameter of the circle is approximately **2,376.06 miles**.
