In the equation (x+2) ^2 + (y-3) ^2=4, the radius of the circle is

center = (-2, 3)

radius = 2

Step-by-step explanation:

(x+2) ^2 + (y-3) ^2 = 4

Use the formula: (x - h) ^2 + (y - k) ^2 = r^2

where (h, k) = center, radius = r

(x - (-2)) ^2 + (y - 3) ^2 = 4 = (2) ^2

center = (-2, 3)

radius = 2
