Answer:
The center of the circle is c=50 and radius of the circle is
Step-by-step explanation:
Given circle equation is
Equation (1) can be written as
we know that the equation of the circle is of the form
with centre (-g,-f) and radius=
when, g,f and c are constants
Now comparing the (2) and (3) equations we get 2g=-4
and
Now to find the centre and radius of the given circle equation, substituting the values of g,f,c in the formulae of centre and radius
centre=(-g,-f)
=(-(-2),-7)
centre=(2,7)
Radius=
=
=
=
Radius=
The center of the circle is c=50 and the radius of the circle equation
