Answer 1

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

\[ C = \pi \times d \]

where \( C \) is the circumference and \( d \) is the diameter. Given that the diameter is 4.5 miles and you are using \( \pi \approx 3.14 \), plug in the values:

\[ C = 3.14 \times 4.5 \]

Calculating that:

\[ C = 14.13 \text{ miles} \]

So, the estimated circumference to the hundredths place is:

14.13 miles.
