Recall that the distance, d, between any two points (x1, y1) and (x2, y2) is given by the following formula:
d = √((x1 - x2)2+(y1 - y2)2)
Assuming that the two given endpoints are on the circle, the diameter of the circle is the distance between these two endpoints. That is, with the following given endpoints of a circle:
Point 1: (x1, y1) = (7, -10) and Point 2: (x2, y2) = (33, -10)
The diameter of the circle is given by the distance between these two points:
d = √((7 - 33)2+(-10 - (-10))2)
= √((-26)2+(0)2)
= √((-26)2)
= √(676)
= 26

Diameter=sqrt[(x2-x1)^2+(y2-y1)^2]. (7,-10) and (33,-10) are the coordinates of the two points. The value you find is the diameter, d. You want the radius, r, so just divide the diameter by 2
