To find the diameter of a circle when given 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 \(d\):
\[ d = \frac{C}{\pi} \]
Given that the circumference \(C\) is 7,459 miles and using \(\pi \approx 3.14\):
\[ d = \frac{7,459}{3.14} \]
Now, performing the calculation:
\[ d \approx \frac{7,459}{3.14} \approx 2,375.16 \]
Rounding to the nearest hundredths place, the diameter is approximately:
\[ \text{Diameter} \approx 2,375.16 \text{ miles} \]
