Answer:

[tex](x-4)^2+(y+3)^2=9[/tex]

Step-by-step explanation:

Standard Form equation of a circle with center (h, k) and radius r:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Plug in given values: h = 4, k = -3, r = 3.

[tex](x-4)^2+[y-(-3)]^2=3^2\\\\(x-4)^2+(y+3)^2=9[/tex]

The tricky part can be the sign in the y squard term:  y - (-3) = y + 3.
