Answer:
[tex]x^2 + (y-8)^2= 81[/tex]
Step-by-step explanation:
the equation of a circle with a center at (0, 8) and a radius of 9.
To frame the equation of the circle we use center radius form of equation
[tex](x-h)^2 + (y-k)^2= r^2[/tex]
Where (h,k) is the center and 'r' is the radius
Given center is (0,8) and radius = 9
h = 0 , k= 8 and r= 9
Plug in all the values
[tex](x-h)^2 + (y-k)^2= r^2[/tex]
[tex](x-0)^2 + (y-8)^2= 9^2[/tex]
[tex]x^2 + (y-8)^2= 81[/tex]
