Verified answer
K = 108 m : 300K = 36 cm
K = 22/7 X d
36 = 22/7 X d
d = 36 : 22/7
d = 11,45 cm
Maaf kalau salah
K = phi.d
= 3,14 x 108
=339,12 m
jadi dalam jarak 339,12 m, ban beputar 300X
berarti dalam 1 m ban perputar 1,1304X => dibulatkan aja jadi 1
jadi tiap 1 m ban berputar 1x
2. 1m = 100cm => ini keliling ban motor
rumus keliling = phi.d
100 = 3,14 . d
d = 100/3,14 = 31,8cm
kurang lebihnya begitu. hasil bisa berbeda tergantung pembulatan
