Keliling roda x 200 = π . d x 200 = 22/7 . 70cm x 200 = 220 cm x 200 = 44.000 cm = 440 m

R=35 keliling = 2.22/7.35 = 220 cm jadi jika bola berputar 200 kali mka 220 x200 = 44000 (c)
= π . d x 200
= 22/7 . 70cm x 200
= 220 cm x 200
= 44.000 cm
= 440 m
keliling = 2.22/7.35 = 220 cm
jadi jika bola berputar 200 kali
mka 220 x200 = 44000 (c)
