for a given centre of (h,k) and radius r, the equation is
(x-h)^2 + (y-k)^2 = r^2
use your information to form the equation.
A circle is centered at (2, -5) and has radius 3. Write its equation in standard form.

(x-2)^2+[y-(-5)]^2=r^2
(x-2)^3+(y+5)^2=3^2
(x-2)^3+(y+5)^2=9
(x-2)^3+(y+5)^2=3^2
(x-2)^3+(y+5)^2=9
