Roda menggelinding sebanyak 50 kali berarti roda telah melintasi papan sepanjang 314 cm x 50 = 15700 cm
2. K = 22/7 x 14 = 44 cm n = j/k = 88/44 = 2 kali

1. k = 3,14 x d = 3,14 x 100 = 314 cm j = k x n = 314 x 50 = 15700 cm / 157 m 2. k = 22/7 x 14 = 44 cm n = j/k = 88/44 = 2 kali 3. k = j/n = 8800/1000 = 8,8 cm k = 3,14 x d 8,8/3,14 = d
Keliling roda (K) = 2πr = 2 . 3,14 . 50 = 314 cm

2. K = 22/7 x 14 = 44 cm
n = j/k = 88/44 = 2 kali
j = k x n = 314 x 50 = 15700 cm / 157 m
2. k = 22/7 x 14 = 44 cm
n = j/k = 88/44 = 2 kali
3. k = j/n = 8800/1000 = 8,8 cm
k = 3,14 x d
8,8/3,14 = d
