## Problem 1123

Write the standard form equation of a circle with a center at (-3, 4) and a radius of 4.

**Solution:-**

Substitute the coordinates and write in standard form:

(x -h)^{2} + (y – k)^{2} = r^{2}

So the equation is

=> (x +3)^{2} + (y – 4)^{2} = 4^{2}

=> (x +3)^{2} + (y – 4)^{2} = 16

^{ }
