d B = 35 cm
jarak = 220 m = 22000 cm
keliling roda = πd
keliling roda A = 22/7 x 140 = 440 cm
keliling roda B = 22/7 x 35 = 110 cm
banyak putaran roda B = jarak / keliling roda B
= 22000 / 110
= 200 kali (D)
semoga membantu ya :)
Kel B = d
= 22/7 × 35
= 110cm
Cari banyaknya roda B berputar dalam 220m
220m = 22.000cm
jarak ÷ keliling B = banyaknya putaran
22.000 ÷ 110 = 200 kali putaran
