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)=(0,5)" and r=d/2=20/2=10#
#rArr(x-0)^2+(y-5)^2=10^2#
