Answer:

[tex](x- 2)^{2}  + (y + 10)^{2}  = 9[/tex] is the equation of the circle.

Step-by-step explanation:

Center of the circle = (2, -10)

Radius = 3

General Form of Circle Equation :

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

where, (h,k) are the center coordinates and r is the radius of circle.

So, substituting (h,k) with (2, -10) and r =3 in the above equation,

we get

[tex](x- 2)^{2}  + (y - (- 10))^{2}  = 3^{2}[/tex]

or, [tex](x- 2)^{2}  + (y + 10)^{2}  =  9[/tex]  is the required equation.
