Answer 3

I just don't know how to find the middle point

Answer 4

what is the standard form of a circle? Plug the center and the point that's passing through in that formula.

Member this?
\[(x-h)^2+(y-k)^2=r^2\]

Here's what you have to plug in
Center (3, - 2):
h = 3 and k = - 2
Point (0, 2):
x = 0 and y = 2

Now solve for the radius.
