whongaliembanyak putaran = jarak : keliling roda = 100 m : 2 π r = 100 m : 2 . 3,14 . 25 = 100 m : 157 cm = 10.000 cm : 157 cm = 63,69 jadi, banyak putaran minimal 64 putaran
=157 cm
Banyak putaran= 10.000/157 =64 kali
= 100 m : 2 π r
= 100 m : 2 . 3,14 . 25
= 100 m : 157 cm
= 10.000 cm : 157 cm
= 63,69
jadi, banyak putaran minimal 64 putaran
