Observe the pie diagram given below .It shows the percentages of number of vehicles passing a signal in a town between 8 am and 10 am.

Find the central angle for each type of vehicle.

Answer

Cars : `108^(@) `, Tempos : `43^(@)`, Buses : `29^(@)`, Autorickshaws : `36^(@)`, Two wheelers : `144^(@)`.

Explanation

(i) The central angle for cars ` = (30%)/100 xx 360^(@) = 108^(@)`
(ii) The central angle for tempos
` = (12%)/100 xx 360^(@) = 43.2 approx 43^(@)`
(iii) The central angle for buses
` = (8%)/100 xx 360^(@) = 28.8 approx 29^(@)`
(iv) The central for autorickshaws
` = (10%)/100 xx 360^(@) = 36^(@)`
(v) The central angle for two wheelers
` = (40%)/100 xx 360^(@) = 144^(@)`
