Solution:
A chord of a circle is a straight line segment whose both endpoints lie on the circle. The longest chord which passes through the centre of the circle is known as diameter.
The portion of a circle enclosed by two radii is known as the sector. The segments of a circle are the region bounded by a chord and the arc subtended by the chord.
a) CP is a chord which is not the diameter of the circle because it does not pass through the centre. [1 mark]
b) Shaded sectors OAC and OPB are

c) The shaded smaller segment of the circle formed by CP is
