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 of the circle. Given that the diameter \(d\) is 3.25 meters and we are using \( \pi \approx 3.14 \), we can plug in the values:
\[ C = 3.14 \times 3.25 \]
Now, let's do the multiplication step-by-step:
-
Multiply 3.14 by 3.25:
\[ 3.14 \times 3.25 = 10.205 \]
-
Round to the hundredths place:
The number 10.205 rounds to 10.21 when rounding to the hundredths place, because the third decimal (5) causes us to round up.
So, the estimated circumference of the circle with a diameter of 3.25 meters is:
\[ \text{Circumference} \approx 10.21 \text{ meters} \]
Among the provided responses, the correct answer is 10.21 meters.
