The diameter … WebWe can also find the radius of the circle if we wish. It is simply half of the diameter, which is given by the distance formula: D = √ ( (x2 – x1)2 + (y2 – y1)2) D = √ ( (6 – 0)2 + (-8 – 0)2) D = √ ( (6)2 + (-8)2) D = √ (36 + 64) D = √ (100) D = 10 So the diameter is 10, and the radius is 5.
