2 Answers
Equation of circle is
Explanation:
The center-radius form of the circle equation is
Hence equation of circle is
Equation of circle is

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)=(-5,8)" and "r=6#
#(x-(-5))^2+(y-8)^2=6^2#
#rArr(x+5)^2+(y-8)^2=36larrcolor(blue)"is the equation"#
