To find the circumference of a circle in terms of \(\pi\), we use the formula:
\[
C = 2\pi r
\]
where \(C\) is the circumference and \(r\) is the radius of the circle.
Given that the radius \(r\) is 13 cm, we can substitute this value into the formula:
\[
C = 2\pi \times 13
\]
\[
C = 26\pi
\]
Thus, the circumference of the circle in terms of \(\pi\) is:
\[
\boxed{26\pi} \text{ cm}
\]
\[
C = 2\pi r
\]
where \(C\) is the circumference and \(r\) is the radius of the circle.
Given that the radius \(r\) is 13 cm, we can substitute this value into the formula:
\[
C = 2\pi \times 13
\]
\[
C = 26\pi
\]
Thus, the circumference of the circle in terms of \(\pi\) is:
\[
\boxed{26\pi} \text{ cm}
