Answer:
Step-by-step explanation:
The standard form of a circle is
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:
which simplifies a bit to
