Explanation:
#"the standard form of the equation of a circle 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 is"#
#"the radius"#
#"here "(a,b)=(7,0)" and "r=10#
#rArr(x-7)^2+(y-0)^2=10^2#
#rArr(x-7)^2+y^2=100larrcolor(red)"equation of circle"#
