The diagram below shows the sector of a circle OAB, with centre O. The angle at the centre of the sector, AOB, is 1.3 radians. The shaded region in the diagram is the segment bounded by the arc AB and the chord AB. 1.3 rad O Given that the difference between the perimeter of sector OAB and the perimeter of triangle OAB is 1.05 cm, find the area of the shaded region. Give your answer correct to 3 significant figures
