jawab :
PERTAMA CARI KELILING RODA :
K = π D
= 22/7 . 56
= 22 . 8
= 176 cm
maka banyak putaran :
= 1,76 km / 176 cm
= ( 1,76 × 100.000 ) / 176 cm
= 176.000 cm / 176 cm
= 1.000/1
= 1.000 putaran => C
Penjelasan dengan langkah-langkah:
jarak = 1,76 = 176.000
keliling roda
= πd
= 22/7 × 56
= 22 × 8
roda berputar sebanyak :
= 176.000 ÷ 176
= 1.000 kali
opsi c
