         1.   Find the difference of the areas of two segments of a circle formed by a chord of length 5 cm
              subtending an angle of 90° at the centre.
         2.   Find the area of the minor segment of a circle of radius 14 cm, when the angle of the corresponding
              sector is 60°.












         3.   In a circle of radius 21 cm, an arc subtends an angle of 60° at the centre. Find:
                  (i) the length of the arc
                  (ii) area of the sector formed by the arc
                  (iii) area of the segment formed by the corresponding chord
         4.   A chord of a circle of radius 15 cm subtends an angle of 60° at the centre. Find the areas of the
              corresponding minor and major segments of the circle. (Use π = 3.14 and √3 = 1.73)

         5.   A round table cover has six equal designs as shown in below figure. If the radius of the cover is 28
                                                                                2
              cm, find the cost of making the designs at the rate of ? 0.35 per cm  . (Use √3 = 1.7)














         6    CASE STUDY: Pookalam is the flower bed or flower pattern designed during Onam in Kerala. It is
              similar as Rangoli in North India and Kolam in Tamil Nadu. During the festival of Onam, your school is
              planning to conduct a Pookalam competition. Your friend who is a partner in competition, suggests
              two designs given below. Observe these carefully.
