Answer 1

@jdoe0001 can you help with this?

Answer 2

hmmm what would be the coordinates for the center of the circle?

Answer 3

@jdoe0001 5.5 & 4

Answer 4

yeap

so the center of it is at (5.5, 4)
and the "radius" is obviously 3.5
from 2 to 9, 7 units, half that, 3.5 = r
thus \(\bf (x-{\color{brown}{ h}})^2+(y-{\color{blue}{ k}})^2={\color{purple}{ r}}^2

\qquad center\ ({\color{brown}{ h}},{\color{blue}{ k}})\qquad
radius={\color{purple}{ r}}
\\ \quad \\
thus\\ \quad \\ (x-{\color{brown}{ 5.5}})^2+(y-{\color{blue}{ 4}})^2={\color{purple}{ 3.5}}^2

\qquad center\ ({\color{brown}{ 5.5}},{\color{blue}{ 4}})\qquad
radius={\color{purple}{ 3.5}}\)
