You can put this solution on YOUR website! distance = 3cm
The chord and the circle's radius form a right triangle, with the radius being the hypotenuse, half of the chord being one side, and the distance from the circle's center to the chord being the 3rd side. This is a 3-4-5 right triangle, so the distance from the circle's center to the chord is 3 cm.
