Kelas 8 MatematikaBab Lingkaran
Panjang busur = 88
α/360° . 2 . π . r = 88
120°/360° . 2 . 22/7 . r = 88
r = 88 . 7 . 360° / (120° . 2 . 22)
r = 42 cm

Jawabannya:Mapel. : Matematika
Bab. : Lingkaran
Pembahasan:
alfa/360°. 2πr = 88
120°/360°. 2. 22/7. r = 88
1/3. 2. 22/7. r = 88
2/3. 22/7. r = 88
44/21. r = 88
r = 88. 21/44
r = 1848/44
r = 42 cm → Jwbnya
