Answer:
[tex](x - a)^{2} + (y - b)^{2} = m^{2}[/tex]
Step-by-step explanation:
The equation of a circle has the following format:
[tex](x - x_{0})^{2} + (y - y_{0})^{2} = r^{2}[/tex]
In which r is the radius(half the diameter) and the centre is the point [tex](x_{0}, y_{0})[/tex]
In this question:
Center (a,b), so [tex]x_{0} = a, y_{0} = b[/tex]
Radius m
Then
[tex](x - a)^{2} + (y - b)^{2} = m^{2}[/tex]
