find Circumference of Circle, given radius

\(\displaystyle C\; = \;\Pi \; \times \;d\)

Is the equation to find the circumference of a circle.

You know the radius is 6. The diameter is twice the radius. This makes the diameter 12.

\(\displaystyle C\; = \;\Pi \; \times \;12 \cr
C\; = \;37.7 \cr\)

How do I find the circumference of a circle if the radius is 6? :?:
sally, WHY do you not know that? Absent from math class?
