Banyak putaran = 100 jarak = 176 m = 17600 cm a) jarak = banyak putaran x keliling roda keliling roda = jarak/banyak putaran = 17600/100 = 176 cm πd = 176 22/7 x d = 176 d = 176 x 7/22 d = 56 cm b) r = 56 : 2 = 28 cm luas roda = πr² = 22/7 x 28 x 28 = 2.464 cm²
semoga membantu ya :)

jarak nya kan 176 cm ?? kok jdi 176 m ?
luas permukaanya saya lupa maafya
jarak = 176 m = 17600 cm
a) jarak = banyak putaran x keliling roda
keliling roda = jarak/banyak putaran
= 17600/100
= 176 cm
πd = 176
22/7 x d = 176
d = 176 x 7/22
d = 56 cm
b) r = 56 : 2 = 28 cm
luas roda = πr²
= 22/7 x 28 x 28
= 2.464 cm²
semoga membantu ya :)
