The formula for the circumference of a circle is:
[tex]C=2\pi r[/tex]Where
C is the circumference
r is the radius
We are given r = 12, substituting it into the formula, we have:
[tex]\begin{gathered} C=2\pi r \\ C=2\pi(12) \\ C=24\pi \\ C\approx75.40\text{ cm} \end{gathered}[/tex]Answer75.40 centimeters
