Hey! Start by finding the radius. We will assume that point
is the center point of the circle, so the radius is the distance between points
and
.
Let's use the distance formula, substituting in the known values:

Simplify:

Now, we'll use the formula for the circumference of a circle, substituting in the known value:

D! Because 2x4=8 and you would have to do that twice and then 1/2x4x6=12 and you would do that twice and 6x2=12
