To calculate the length of a steel ring that fits around a pipe with a diameter of 5 centimeters, you can use the formula for the circumference of a circle:
\[
C = \pi \times d
\]
where \(C\) is the circumference, and \(d\) is the diameter.
Plugging in the value for the diameter:
\[
C = \pi \times 5 \, \text{cm}
\]
Using the approximate value of \(\pi \approx 3.14\):
\[
C \approx 3.14 \times 5 \, \text{cm} \approx 15.7 \, \text{cm}
\]
So, the steel ring needs to be approximately \(15.7\) centimeters long to fit around the pipe.
