(x-3)²+y²=9
(x-3)²+(y-0)²=3²
The equation can be written in the form (x-p)²+(y-q)²=r², so it represents a circle with the radius r=3 and the center (3, 0)

Hope my answer helped u :)

Answer:

  • Center = (3, 0)
  • Radius = 3
  • Graph = see below

Concept:

Here, we need to know the idea of the circle equation.

Circle equation: (x - h)² + (y - k)² = r²

(h, k) = center

r = radius

x = variable

y = variable

Solve:

Given expression

(x - 3)² + y² = 9

Find the point of the center

(h, k) =
\boxed{(3,0)}

Find the length of the radius

r² = 9


\boxed{r=3}

Hope this helps!! :)

Please let me know if you have any questions
