Explanation:
The standard form of the equation of a circle is.
#color(red)(|bar(ul(color(white)(a/a)color(black)((x-a)^2+(y-b)^2=r^2)color(white)(a/a)|)))#
where (a ,b) are the coordinates of the centre and r, the radius.here a = 3, b= 0 and r = 1
substitute these values into the equation.
#(x-3)^2+(y-0)^2=1^2#
#rArr(x-3)^2+y^2=1" is the equation of the circle"#
