Answer:
Explanation:
From the graph, first, determine the centre and radius of the circle.
• The centre of the circle, (h,k)=(1,2)
,
• The radius of the circle, r = 4
Substitute these values into the general equation of a circle:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
This gives the equation of the circle above as:
