the distance d between these two points is a radius r
Solved by pluggable solver: Distance Formula to determine length on coordinate plane
The distance (d) between two points is given by the following formula:

d=sqrt%28%28x2-x1%29%5E2+%2B+%28y2-y1%29%5E2%29

Thus in our case, the required distance is
d=sqrt%28%28-6--3%29%5E2+%2B+%287-4%29%5E2%29=+4.24264068711928+


For more on this concept, refer to Distance formula.


so, r=4.243
