You should know the equation of a circle : under root (x2-x1)2 + (y2-y1)2 = r2
Where r is the radius.
(x1,y1) is the centre.

You are given 2 end points forming the diameter.

Find the radius by using distance formula and dividing that by 2.
Find the centre by finding the mid-point of those 2 given points.
and then just put them in the equation of the circle.

Understood? :)
