    find the length of the line joining the 2 points and divide the answer by 2

    the formula for the length of a line joining (x1,y1) and (x2,y2) = sqrt [(x2-x1) ^2 + y2-y1)^2] which is the Pythagoras theorem

    hope this helps Use the distance formula to find the length of the diameter between these two points. d = √[ (-2-3)^2 + (4-8)^2 ] d = √[ (-5)^2 + (-4)^2 ] d = √( 25 + 16 ) d = √( 41 ) = 6.40312424 = diameter. the radius is 1/2 the diameter. 6.40312424/2 = 3.20156212.
