1. In which year was Kenya's exports highest?     
2. Using a radius of 5cm, draw a pie-chart to represent the data on Kenya's exports in 2009.
3. State two advantages of using pie charts to represent data.

Answer 1

1. 2010
2.  Total =  100,975 + 18,961 + 162,732 + 59,236 + 3,044
            =344,948
   Europe   100,975  × 360° =105.38  =105°
                344,948
   America  18,961   × 360° =19.78  =20°
                344,948
   Africa   162732  × 360° =169.83  =170°
              344,948
   Asia    59236  × 360° = 61.82   =62°
           344,948
   Others    3044    × 360° =3.17  =3°
              344,948
