$\lparen x-30)^{\text{ }}\text{ + \lparen y-15\rparen = 9}$

Step-by-step explanation:

The equation form of a circle is given by

$\lparen x-h)^2+\text{ \lparen y-k\rparen}^2\text{ = r}^2$

with

(h,k) being the coordinates of the center of the circle : (30, 15)

and r being the radius of the circle: 18 / 2 = 9

$\begin{gathered} \operatorname{\lparen}x-30)^2\text{ + \lparen y - 15\rparen}^2\text{ = 9}^2 \\ \sqrt{\operatorname{\lparen}x-30)^2}\text{ + }√(\left(y-15\rparen^2\right?)\text{ = }√(81) \\ \lparen x-30)\text{ + \lparen y-15\rparen = 9} \end{gathered}$
