Circle divided into sectors by two chords through the centre. The two larger sectors are shaded grey. A 40-degree angle is marked at the centre of the circle for one of the unshaded sectors, and a radius of 2 is labelled in another sector.

The diagram shows a circle of radius 2 cm.

The circle has been divided into four sectors by drawing two chords through the centre. The two larger sectors are shaded and the two smaller sectors are left unshaded.

The angle of one of the unshaded sectors is 40°.
