Jawaban:
100 putaran
Penjelasan dengan langkah-langkah:
Jumlah putaran = jarak/keliling roda
..
Jarak = 132 m = 13200 cm
Keliling
22/7 × 2 × 21
22/7 × 42
= 132 cm
Jumlah putaran
= 13200/132
= 100 putaran

keliling
K = 2πr
K = 2 × 22/7 × 21
K = 2 × 22 × 3
K = 2 × 66
K = 132 cm
putaran
jarak/keliling
132 m/132 cm
= (132 × 100) cm/132 cm
= 13.200 cm/132 cm
