Answer
a) The center-radius form of the circle equation is
$x^2$ + $y^2$ = $36$
b) Refer to Graph I for the graphing.
Work Step by Step
Center = Origin (0, 0) and Radius r = 6
a) The center-radius form of the circle equation is
$x^2$ + $y^2$ = $6^2$
$x^2$ + $y^2$ = $36$
b) Refer to Graph I for the graphing.
