<h3>
What is the equation of a circle?</h3>
- The equation of a circle of radius r and center
is given by:

Item a:
- Center C(5,2), hence
.
The point at the circumference is A(11,10), hence:



Hence:

Item b:
- Center C(-2,-5), hence
.
The point at the circumference is A(3,-17), hence:



Hence:

Item c:
- Center C(5,-1), hence
.
The point at the circumference is A(-2,-5), hence:



Hence:
