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.
The approximate circumference of a circle is 7,459 miles. What is the radius rounded to the nearest hundredths place? Use 3.14 for PI and express your answer to the tenths place. Use the formula sheet provided.(1 point)
