Diagram Lingkaran jml ternak
* kambing =a ,unggas =b, kerbau =c ,sapi= d*
a+b+c+d= 1440
a = 90°
b = 90°
c = 30°
Dit
a. Jumlah a (unggas)?
b. Jumlah sapi?
Jawab
a = 90°/360° x 1440 = 1/4 .1440 =360
b = 90°/360° x 1440 = 1/4 .1440 = 360
c = 30°/360° x 1440 = 1/12 .1440 =120
d =( 360°-(90°+90°+30°)) / 360° x 1440 = 150°/360° .1440 = 5/12 .1440 = 600 ekor
Jadi,
a) 360 ekor
b) 600 ekor
