To find the circumference of a circle, you can use the formula:
\[ \text{Circumference} = \pi \times \text{Diameter} \]
Given that the diameter is 4.5 miles and using 3.14 for π:
\[ \text{Circumference} = 3.14 \times 4.5 \]
Now, calculate that:
\[ \text{Circumference} = 3.14 \times 4.5 = 14.13 , \text{miles} \]
So the estimated circumference to the hundredths place is 14.13 miles.
