Answer:

Step-by-step explanation:
step 1
Find the diameter of the circle
the formula to calculate the distance between two points is equal to

we have
substitute the values




step 2
Find the center of the circle
The center is the midpoint of the diameter
The center is equal to


step 3
Find the equation of the circle
The equation of the circle in center radius form is equal to

we have
(h,k)=(3,2)
---> the radius is half the diameter
substitute


The first thing we are going to do to graph our equation is solve them for

:
For our first equation:



For our second equation:


Now, we just need to use the graphing utility to graph our equations:


We can conclude that the graph of the equations is:
