Which choice correctly describes the circle with equation x

Which choice correctly describes the circle with equation (x - 3)^2 + (y + 3)^2 = 4 center: (3, -3) r = 2 center: (-3, 3) r = 2 center: (3, -3) r = 4 center: (-3, 3) r = 4

Solution

Given equation for circle is (x - 3)^2 + (y + 3)^2 = 4

General equation of circle is (x - a)^2 + (y - b)^2 = r^2 where center = (a, b) and radius = r

On comparing, center = (3, -3) and radius = r = 2

Option a) is correct.
