Answer 1

To find the circumference \( C \) of a circle using the formula \( C = \pi d \), we first need to calculate the diameter \( d \) using the radius \( r \).

The diameter is given by the formula:
\[
d = 2r
\]

For a radius \( r \) of 97 m:
\[
d = 2 \times 97 = 194 \text{ m}
\]

Now we can calculate the circumference using \( C = \pi d \):
\[
C = \pi \times 194 \approx 3.14 \times 194 \approx 609.26 \text{ m}
\]

Rounding to the nearest whole number, the circumference is approximately:
\[
C \approx 609 \text{ m}
\]

Thus, the circumference of the circle is **609 m**.
