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 \( d \) is 3.25 meters and using \( \pi \) as 3.14:
\[ C = 3.14 \times 3.25 \]
Now, let's calculate it:
\[ C = 3.14 \times 3.25 = 10.205 \text{ meters} \]
Now, rounding to the hundredths place:
The circumference \( 10.205 \) meters rounds to \( 10.21 \) meters.
Therefore, the correct answer is 10.21 meters.
