= 3,14 x 60
= 188,4
Jarak yg ditempuh = K. Lingkaran x Bnyak Putaran
= 188,4 x 100
= 18.840 cm
diameter = 60 cm
berputar = 100 kali
π = 3,14
dity :
jarak yg ditempuh roda tsb...??
jwb :
⇔ keliling = 2 π r
keliling = 2 × 3,14 × 30
keliling = 188,4 cm
⇔ jarak yang ditempuh :
⇒ banyaknya putaran × keliling
⇒ 100 × 188,4
⇒ 18.840 cm
⇒ 188,8 m
