Answer:
The circumference of a circle with radius [tex]\pi[/tex] is [tex]2\pi^2[/tex] units.
Step-by-step explanation:
The circumference of a circle is defined by the equation [tex]C=2\pi r[/tex], where [tex]C[/tex] stands for the circumference and [tex]r[/tex] stands for the radius.
Substituting the variables with the known values, we get the following:
[tex]C=2\pi(\pi)\\C=2\pi^2[/tex]
