Question 1109404: the distance of a chord of a circle of a radius 5cm from the centre of the circle is 4 cm calculate the length of the chord
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! If one draws the circle, the radius and the chord, the radius is 5 and the hypotenuse of a chord 4 cm away from the center. Therefore, half the distance of the chord is 3 cm (3-4-5 right triangle), and the whole chord is 6 cm long, twice the 3 cm, since the distance to the center is a perpendicular bisector of the chord.
