Jika panjang busur AB = 44 dan r= 14, Tentukan luas juring AOB!
tolong yaa, btw makasii![]()
tolong yaa, btw makasii
Materi : Unsur - Unsur Lingkaran
Besar Sudut Juring
a/360° = AB /( Ο × d )
a = 44/( 22/7 × 28 ) × 360°
a = 44/88 × 360°
a = 180°
Luas ½ Lingkaran
= ½ × Ο × r²
= ½ × 22/7 × 14 cm × 14 cm
= 11 × 2 cm × 14 cm
= 11 × 28 cm²
= { 308 cm² }
Semoga bisa membantu
