Answer:
[tex]x^2+(y-1)^2=225[/tex]
Step-by-step explanation:
we know that
The equation of the circle in center radius form is equal to
[tex](x-h)^2+(y-k)^2=r^2[/tex]
where
(h,k) is the center of the circle
r is the radius of the circle
In this problem we have
[tex](h,k)=(0,1)\\r=15\ units[/tex]
substitute
[tex](x-0)^2+(y-1)^2=15^2[/tex]
[tex]x^2+(y-1)^2=225[/tex]
