A circle of D diameter has a point P internally. From this point three lines at 120 degree spacing radiate to the circumference of the circle, thus forming three areas, one of which is a quarter of the the total area of the circle, and another area is one third of the total area of the circle. In terms of D find an expression for the distance from the centre of the circle to point P.
