How do you find the center and radius for #x^2 + y^2 = 36#?
centre = (0 ,0), radius = 6
The standard form of the equation of a circle is.
where (a ,b) are the coordinates of the centre and r, the radius.
The equation here can be expressed in this form, that is
By comparison with the standard equation.
centre = (0 ,0) and radius = 6
