Question 1106555
The circle centered at (1,2) with a radius of 5 is,
{{{(x-1)^2+(y-2)^2=5^2}}}
So choose any x and solve for y.
As an example, {{{x=1}}},
{{{(1-1)^2+(y-2)^2=5^2}}}
{{{y-2=0 +- 3}}}
{{{y=2 +- 3}}}
{{{y=5}}} and {{{y=-1}}}
So,
(1,5) and (1,-1) are two points. 
Find two more by choosing another value for x.
