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 \( d = 3.25 \) meters and using \( \pi \approx 3.14 \), we can substitute into the formula:

\[ C = 3.14 \times 3.25 \]

Now, let's do the multiplication:

\[ C = 3.14 \times 3.25 = 10.225 \]

Rounding to the hundredths place, the circumference is:

\[ C \approx 10.23 \text{ meters} \]

However, since the options provided all have different values, and not the calculated one, I assume you need to pick one of them.

In this case, the closest estimated value to the calculated circumference of 10.23 meters (if rounded again would be often approximated) would yield none of the responses would fit exactly.

If you were to look for potential rounding down, then the closest would be 10.22 meters or approximating options from above seems like the correct answer for available ones.

So the answer is:

10.22 meters
