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 3.25 meters and using \( \pi \approx 3.14 \):
\[
C = 3.14 \times 3.25
\]
Now, let's calculate that:
\[
C \approx 3.14 \times 3.25 = 10.205
\]
Rounding 10.205 to the hundredths place gives us 10.21.
So, the correct response is:
**10.21 meters**.
\[
C = \pi \times d
\]
where \(C\) is the circumference and \(d\) is the diameter. Given that the diameter is 3.25 meters and using \( \pi \approx 3.14 \):
\[
C = 3.14 \times 3.25
\]
Now, let's calculate that:
\[
C \approx 3.14 \times 3.25 = 10.205
\]
Rounding 10.205 to the hundredths place gives us 10.21.
So, the correct response is:
**10.21 meters**.
