The formula for the circumference of a circle is C = 2 * π * r, where C is the circumference, π is approximately 3.14, and r is the radius.

Given that the approximate circumference of the circle is 7,459 miles, we can use the formula to find the radius:

7,459 = 2 * 3.14 * r
r = 7,459 / (2 * 3.14)
r = 1187.713... (rounded to the nearest hundredth)

Therefore, the radius rounded to the nearest hundredth is 1,187.7 miles, which corresponds to the second option.
