Question

What is the standard form of the equation for this circle?

Answer 1

help???

Answer 2

any ideas on what the raidus and center of it are?

Answer 3

hmmm

Answer 4

and so, what's the center coordinates again?

Answer 5

A(4,-5) and 5.5

Answer 6

ohh yes

center is at 4,-5
and radius is 5.5 units long
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 \\
(x-{\color{brown}{ 4}})^2+(y-{\color{blue}{ -5}})^2={\color{purple}{ 5.5}}^2

\qquad center\ ({\color{brown}{ 4}},{\color{blue}{ -5}})\qquad
radius={\color{purple}{ 5.5}}
