The question in the image asks for the circumference of a circle with a diameter \( d = 89 \, \text{cm} \). 

The formula for the circumference \( C \) of a circle is:
\[
C = \pi d
\]

Substituting \( d = 89 \, \text{cm} \):
\[
C = \pi \times 89 \, \text{cm}
\]

Using \( \pi \approx 3.1416 \):
\[
C \approx 3.1416 \times 89 \approx 279.06 \, \text{cm}
\]

Rounding to 1 decimal place, the circumference is:
\[
C \approx 279.1 \, \text{cm}
\]
