the diameter of a circle given the points: (0,11)(-4,7/2) and the radius Apr 18 | Kajin from Plano, TX | 1 Answer | 0 Votes Mark favorite Subscribe Comment
the distance formula is D = rad{((X2-X1)^2)+((Y2-Y1)^2)} . Just plugin the values of your x and y. Then the radius is half of the diameter, so divide your distance by 2 and that will be your radius of the circle. Apr 18 | Jaudat R. Comment
