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 = 8
#(x+3)^2+(y-0)^2=64# which simplifies to
#rArr(x+3)^2+y^2=64" is the equation of the circle"#
