Diketahui panjang busur AB adalah 60 cm dan ∠AOB = 120º. Tentukan keliling !
![]()
Materi : Unsur - Unsur Lingkaran
Keliling Juring AOB
AB = ( a/360° )( π × d )
60 cm = ⅓( K )
K = 60 cm × 3
{ K = 180 cm }
Semoga bisa membantu

Penyelesaian:
Busur AB=60cm
AOB=120°
----------------------------------------
Maka
Busur AB=120°/360°×k
60=1/3×k
60×3=k
k=180cm
----------------------------------------
