Which equation represents a circle with center Z (-3,5) and a radius of 4 units?

(x+3) ^2 + (y-5) ^2=16

Step-by-step explanation:

Equation of a circle is (x-h) ^2 + (y-k) ^2=r^2 where r is the radius and (h, k) is the center.

Given a center of (-3,5) the equation of the circle so far is (x+3) ^2 + (y-5) ^2=r^2

Given a radius of 4, the equation of the circle is (x+3) ^2 + (y-5) ^2=16 (as 4^2 is 16)
