Answer:

Explanation:

The standard form of a circle is


(x-h)^2+(y-k)^2=r^2 where h and k are the center of the circle and r is the radius. Our center is located at (0, 1), so h = 0 and k = 1. Going from the center straight up of down we have to move 2 units to get to a point on the outside of the circle, so r = 2. Filling in our equation:


(x-0)^2+(y-1)^2=2^2 which simplifies a bit to


x^2+(y-1)^2=4
