jika luas juring BOC = [tex] {50cm}^{2} [/tex] , luas juring AOD adalah... tolong sama caranya ya, mksh :))

Kelas 8 Matematika
Bab Lingkaran

Luas juring AOD/luas juring BOC = ∠AOD/∠BOC 
Luas juring AOD/50 = 60°/100°
Luas juring = 50 cm² . 60°/100°
Luas juring = 30 cm²

Luas juring AOD/luas juring BOC = sudut AOD/sudut BOC
•••••/ 50 = 60° / 100°
••••• = 60° / 100° × 50
••••• = 30 cm²
