Answer:
The center is (5,0) and r=9.
Step-by-step explanation:
The standard form of a circle is [tex](x-h)^2+(y-k)^2[/tex] where (h,k) is the center and r is the radius.
On comparing your equation of
[tex](x - 5)^2 + (y-0)^2 = 9^2[/tex], we should see that h=5,k=0, and r=9.
The center is (5,0) and r=9.
Answer:
The center is at (5,0) and the radius is 9
Step-by-step explanation:
(x - 5)^2 + y^2 = 81.
An equation for a circle can be written in the form
(x-h)^2 + (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
Rewriting the equation
(x - 5)^2 + y^2 = 81.
(x - 5)^2 + (y-0)^2 = 9^2
The center is at (5,0) and the radius is 9
