Plis tolong di jawab :'(
langsung aja :
1a]
( AB = 120°/360° × 2 × 3,14 × 24
( AB = 50,24 cm
[ ( AB = panjang busur AB ]
b]
L juring = 120°/360° × 3,14 × 24 × 24
L juring = 602,88 cm^2
2]
L juring COD = 80°/100° × 45
L juring COD = 36 cm^2
3]
( KL = 130°/60° × 24
( KL = 52 cm
[ ( KL = panjang busur KL ]
