Give the equation of the circle that is tangent to the y-axis and Center is (-3,2).

joja [24]

The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. If a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point. hope this helps
