Find the equation of the circle with center at (-1, 3) and radius of 4.

(x+1) ^2 + (y-3) ^2 = 16

Step-by-step explanation:

The equation of a circle is given by

(x-h) ^2 + (y-k) ^2 = r^2

Where (h, k) is the center and r is the radius

(x--1) ^2 + (y-3) ^2 = 4^2

(x+1) ^2 + (y-3) ^2 = 4^2

(x+1) ^2 + (y-3) ^2 = 16
