Answer 1

To calculate 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 \( d \) is 3.25 meters and using \( \pi \approx 3.14 \):

\[ C = 3.14 \times 3.25 \]

Now, let's perform the multiplication:

\[ C = 3.14 \times 3.25 = 10.205 \]

Rounding 10.205 to the hundredths place gives us:

\[ C \approx 10.21 \text{ meters} \]

So the correct response is:

10.21 meters
