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 \( d = 5.75 \) miles and using \( \pi \approx 3.14 \):
\[ C = 3.14 \times 5.75 \]
Now, let's perform the multiplication:
\[ C = 3.14 \times 5.75 = 18.065 \]
Rounding this to the hundredths place, we have:
\[ C \approx 18.07 \]
Therefore, the estimated circumference of the circle is 18.07 miles.
Let's calculate the circumference again using the formula:
\[ C = \pi \times d \]
Given the diameter \( d = 5.75 \) miles and using \( \pi \approx 3.14 \):
\[ C = 3.14 \times 5.75 \]
Now let’s perform the multiplication step by step:
\[ 3.14 \times 5.75 = 18.075 \]
Now, rounding \( 18.075 \) to the hundredths place, we look at the third decimal place (which is 5) and see if we need to round up. Since it's 5, we round up:
\[ C \approx 18.08 \]
So, the estimated circumference of the circle is 18.08 miles.
