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"#
#"the radius is the distance from the centre to "(-2,3)#
#rArrr=sqrt((-2-1)^2+(3-0)^2)=sqrt18#
#rArr(x-1)^2+y^2=18" is the equation"#
