Explanation:
#"the equation of a circle in standard form is"#
#color(red)bar(|ulcolor(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"#
#"is the radius"#
#"here "(a,b)=(-3,-6)" and "r=2#
#(x-(-3))^2+(y-(-6))^2=2^2#
#rArr(x+3)^2+(y+6)^2=4larrcolor(red)"equation of circle"#
