Ican’t find the radius. i have found the center but it’s impossible for me to find the radius.

radius = 2 sqrt(5)

Step-by-step explanation:

We can find the radius from the endpoints

The diameter is the distance between the endpoint

The distance between  a and b is

d = sqrt( (x2-x1)^2 + (y2-y1)^2)

  = sqrt((11-3)^2 +(-8--4)^2)

  = sqrt((8^2+ (-8+4)^2)

   = sqrt(64+-4^2)

   = sqrt(64+16)

   = sqrt(80)

We know that sqrt(a b) = sqrt(a) sqrt(b)

sqrt(80) = sqrt(16) sqrt(5)

                4sqrt(5)

This is the diameter

The radius is 1/2 the diameter

radius  =1/2 (4 sqrt(5))

              radius = 2 sqrt(5)

They did not list the radius.  There is an error with the problem

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce
