Investigate Equation of Circle
A circle can be expressed with the cartesian equation \(\color{blue}{{\left( {x - a} \right)^2} + {\left( {y - b} \right)^2} = {r^2}}\),
where a, b and r are constants.
The circle is centred at \(\color{blue}{(a, b)}\) and has radius \(\color{blue}{r}\).
where a, b and r are constants.
