    This is the form of a circle. Use this form to determine the center and radius of the circle.

    (

    x

    -

    h

    )

    2

    +

    (

    y

    -

    k

    )

    )

    2

    +

    (

    y

    -

    k

    Match the values in this circle to those of the standard form. The variable

    r

    r

    represents the radius of the circle,

    h

    h

    represents the x-offset from the origin, and

    k

    k

    represents the y-offset from origin.

    r

    =

    8

    r

    =

    8

    h

    =

    9

    h

    =

    9

    k

    =

    0

    k

    =

    0

    The center of the circle is found at

    (

    h

    ,

    k

    )

    (

    h

    ,

    k

    )

    .

    Center:

    (

    9

    ,

    0

    )

    (

    9

    ,

    0

    )

    These values represent the important values for graphing and analyzing a circle.
