Consider the circle in the graph.

Loading Graph...

A circle is drawn on the Cartesian coordinate system with axes labeled x and y, both ranging from -5 to 5. The point at the topmost part of the circle farthest from the center is at coordinates $\left(0,2\right)$(0,2). The point at the bottommost part of the circle farthest from the center is at coordinates $\left(0,-2\right)$(0,−2). The point at the leftmost part of the circle farthest from the center is at coordinates $\left(-2,0\right)$(−2,0). The point at the rightmost part of the circle farthest from the center is at coordinates $\left(2,0\right)$(2,0). The coordinates are not explicitly labeled in the image.

a

State the coordinates of the center in the form $\left(a,b\right)$(a,b).

b

State the radius.
