What is the circumference of a circle with a diameter of 4.5 miles? Estimate the circumference to the hundredths place using 3.14 for π

Question

.

Answer 1

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

\[ C = \pi \times d \]

where \( C \) is the circumference and \( d \) is the diameter.

Given that the diameter \( d \) is 4.5 miles and using \( \pi \approx 3.14 \), we can substitute the values into the formula:

\[ C = 3.14 \times 4.5 \]

Now, we calculate:

\[ C = 3.14 \times 4.5 = 14.13 \]

Thus, the estimated circumference of the circle is:

\[ \boxed{14.13} \text{ miles} \]
