diameter lingkaran yg kelilingnya 154cm adl

LINGKARAN
Kelas : 6
Kode mata pelajaran : 2
Bab : 4
Kode : 6.2.4

K = 2 (phi) r

atau

K = (phi) d

K = keliling
phi = 22/7 atau 3,14
r = jari - jari
d = diameter

r = 1/2 diameter
d = 2 jari - jari

K = (phi) d
154 = 22/7 × d
154 = 22d/7
_________×7
1.078 = 22d
_________÷22
49 = d

Jadi, diameter = 49 cm

Jari - jari = 1/2 diameter
1/2 × 49
24,5 cm
