jawabanku yg r = 35.03 itu klo dibulatin yo sama aja 35 si?

ya, kalo pake 3.14, itu malah sulit, kayaknya soalnya salah deh

1. keliling roda = Jarak : n = 2640 : 1200 = 2.2 m = 220 cm panjang jari-jari roda? keliling lingkaran= 2 π r 220 cm = 2 . 3,14 .r 220 = 6,28 r 220: 6,28 = r 35.03 cm = r
a. keliling roda = 246000/1200
= 220 cm
b. keliling = 2 . phi . r
220 = 2. 22/7 . r
220 = 44/7 . r
220 . 7 = 44r
1540 = 44r
r = 35
= 2640 : 1200
= 2.2 m = 220 cm
panjang jari-jari roda? keliling lingkaran= 2 π r
220 cm = 2 . 3,14 .r
220 = 6,28 r
220: 6,28 = r
35.03 cm = r
