To find the length of the steel ring needed to fit around a pipe, you need to calculate the circumference of the pipe. The formula for the circumference \( C \) of a circle is:
\[
C = \pi \times d
\]
where \( d \) is the diameter of the circle.
In this case, the diameter of the pipe is 5 centimeters. Using \( \pi \) (approximately 3.14), we can calculate the circumference:
\[
C = \pi \times 5 \, \text{cm} \approx 3.14 \times 5 \, \text{cm} \approx 15.7 \, \text{cm}
\]
Thus, the steel ring needs to be approximately **15.7 centimeters** long to fit around the pipe.
