Paha777 [63]

Answer:

Center: $(0,9)$

Radius: $15$

Step-by-step explanation:

-According to the following equation, the center would be $(0,9)$ , because the center is known as $(h,k)$ from the equation of a circle. To find the radius, you would only need to square root the simplified radius from the following the equation and you would get the radius 15:

The equation of a circle:

$(x-h)^2+(y-k)^2 =r^2$

The following equation:

$x^2+(y-9)^2 =225$

Center: $(0,9)$ Radius: $\sqrt{225} = 15$
