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"
"is the radius"
"here "(a,b)=(0,0)" and "r=5
(x-0)^2+(y=0)^2=5^2
x^2+y^2=25larrcolor(red)"equation of circle"
