The formula to calculate the circumference \( C \) of a circle is:

\[ C = \pi \times d \]

where \( d \) is the diameter of the circle. Given the diameter \( d = 3.25 \) meters and using \( \pi \approx 3.14 \):

\[ C = 3.14 \times 3.25 \]

Calculating that:

\[ C = 3.14 \times 3.25 = 10.245 \]

Rounding this to the hundredths place, we get:

\[ C \approx 10.25 \text{ meters} \]

However, since the given responses do not include 10.25 meters, we will choose the closest option, which is 10.22 meters.
