Answer 1

To find the radius of a circle when given the circumference, you can use the formula:

Circumference = 2 * π * radius

Given that the circumference is approximately 7,459 miles and π is 3.14, plug in the values and solve for the radius:

7,459 = 2 * 3.14 * radius
7,459 = 6.28 * radius
radius = 7,459 / 6.28
radius ≈ 1,187.73885

Rounded to the nearest hundredth place, the radius is approximately 1,187.7 miles. Therefore, the correct answer is:

1,187.7 miles
