Question

Bantuin jwb dong pliss pake rumus

Answer 1

R kawat = 6 mm
p kawat (t) = 60m = 60.000 mm

V = LA . t
= pi . r2 . t
= 3,14 . 6.6 . 60000
= 3,14 . 36 . 60000
= 6782400 mm kubik = 6782,4 cm kubik

Berat kawat = 6782,4 . 7,8 = 52902,72 gram = 52,9 kg

Answer 2

R=12/2=6 mm= 0,6 cm
t=60 m = 6000 cm

V=πr²t
V=3,14 x 0,6 x 0,6 x 6000
V=6782,4 cm³

Berat kawat
= Volume x berat satuan
=6782,4 x 7,8
=52902 gram
=52,9 kg
