tolong ya susah mtk diagram lingkaran=Tahun=2010,2011,2012,2013,2014,hasil panen (kuintal),2010=20,2011=30,2012=20,2013=15,2014=35

buat diagram lingkaran dengan ketentuan :
jumlah hasil panen = 20+30+20+15+35 =120 kwintal = 360° = 100 %

2010 = 20/120 =1/6 = 1/6 x 360° = 60°
         =persentase = 1/6 x 100% =16,66 % = 17,7 % (pembulatan)

2011 = 30/120 =1/4 = 1/4 x 360° = 90°
         =persentase = 1/4 x 100% =25 %

2012 = 20/120 =1/6 = 1/6 x 360° = 60°
         =persentase = 1/6 x 100% =16,66 % = 17,7 % (pembulatan)

2013 = 15/120 =1/8 = 1/8 x 360° = 45°
         =persentase = 1/8 x 100% =12,5 % 

2014 = 35/120 =35/120 x 360° = 105 °
         =persentase = 35/120 x 100% =29,17 % = 29,2 % (pembulatan)

semoga bantu yaaa
