Answer:
Center: [tex](0,9)[/tex]
Radius: [tex]15[/tex]
Step-by-step explanation:
-According to the following equation, the center would be [tex](0,9)[/tex] , because the center is known as [tex](h,k)[/tex] 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:
[tex](x-h)^2+(y-k)^2 =r^2[/tex]
The following equation:
[tex]x^2+(y-9)^2 =225[/tex]
Center: [tex](0,9)[/tex] Radius: [tex]\sqrt{225} = 15[/tex]
