Find the circumference of the given circle

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:

40.21

Step-by-step explanation:

The circumference of a circle is 2πr; where are is the radius.  The radius is not given but two points

(x1,y1) = (-2,2)

(x2,y2) = (3,-2)

With the two points you can use the distance formula which will be equal to the radius

r =

r =

r =

r = = 6.40

circumference = 2πr = 2π(6.40) = 40.21
