The equation of a circle is centered at (7, 8) and has a radius of 11 [tex]\rm (x-7)^2+(y-8)^2=121[/tex].
What is the equation of a circle?
The circle equation formula refers to the equation of a circle which represents the center-radius form of the circle.
A circle can be represented as;
[tex]\rm (x-h)^2+(y-k)^2=r^2[/tex]
Where; h and k are the center of the circle r is the radius of the circle.
A circle is centered at (7, 8) and has a radius of 11.
The following is the equation for this circle is;
[tex]\rm (x-h)^2+(y-k)^2=r^2\\\\(x-7)^2+(y-8)^2=11^2\\\\(x-7)^2+(y-8)^2=121[/tex]
Hence, the equation of a circle is centered at (7, 8) and has a radius of 11 [tex]\rm (x-7)^2+(y-8)^2=121[/tex].
