To estimate the circumference of a circle, you can use the formula:
\[ C = \pi \times d \]
where \( C \) is the circumference and \( d \) is the diameter of the circle.
Given that the diameter \( d = 5.75 \) miles and using \( \pi \approx 3.14 \), we can substitute these values into the formula:
\[ C \approx 3.14 \times 5.75 \]
Now, let's do the multiplication:
\[ C \approx 3.14 \times 5.75 \approx 18.095 \]
Rounding to the hundredths place, the circumference is approximately:
\[ C \approx 18.10 \text{ miles} \]
So, the estimated circumference of the circle is **18.10 miles**.
\[ C = \pi \times d \]
where \( C \) is the circumference and \( d \) is the diameter of the circle.
Given that the diameter \( d = 5.75 \) miles and using \( \pi \approx 3.14 \), we can substitute these values into the formula:
\[ C \approx 3.14 \times 5.75 \]
Now, let's do the multiplication:
\[ C \approx 3.14 \times 5.75 \approx 18.095 \]
Rounding to the hundredths place, the circumference is approximately:
\[ C \approx 18.10 \text{ miles} \]
So, the estimated circumference of the circle is **18.10 miles**.
