Explanation:
"the equation of a circle in standard form is"
color(red)(bar(ul(|color(white)(2/2)color(black)((x-a)^2+(y-b)^2=r^2)color(white)(2/2)|)))
"where "(a,b)" are the coordinates of the centre and r"
"the radius"
"here "(a,b)=(2,2)" and r=4
(x-2)^2+(y-2)^2=16larrcolor(red)"equation of circle"
