1. diketahui diameter roda 21 cm. jika roda berputar 2.500 kali . tentukan panjang lintasan sang dilalui
liliput01
Diket: D roda = 21 cm n = 2500 kali Dit: panjang lintasan (s)....? K = π D K = 22/7 x 21 K = 66 cm . s = K x n s = 66 x 2500 s = 165000 cm atau s = 1650 m = 1,65 km
D roda = 21 cm
n = 2500 kali
Dit: panjang lintasan (s)....?
K = π D
K = 22/7 x 21
K = 66 cm
.
s = K x n
s = 66 x 2500
s = 165000 cm
atau s = 1650 m = 1,65 km
