Diket sudut AOB = 120°,sudut BOC = 150° dan luas juring AOB = 51 1/3 cm2 dengan (phi) = 22/7. Luas juring BOC adalah...

[tex]= \frac{\ \textless \ AOB}{\ \textless \ BOC} = \frac{ L_{AOB} }{ L_{BOC} } \\ = \frac{120}{150} = \frac{ 51 \frac{1}{3} }{ L_{BOC} } \\ = 120.BOC = 51 \frac{1}{3} . 150 \\ = 120.BOC = 7695 \\ = L_{BOC} = 64 \frac{1}{8} [/tex]

maaf kalau salah.
