Diket Ls=550 cm t=25cm ditanya d...?? Ls=2×π×r×t 550=2×3,14×r×25 550=157r r=550/157 r=3,5 cm
d=2×r =2×3.5 =7

Diket: L selimut = 550 cm2 Tinggi = 25 cm (k=phi x d) Ditanya = Diameter Jawab : L s = K . Tinggi 550 = phi.d . 25 22=phi.d 22= 22/7 d=7 => Jawaban = B
Ls=550 cm
t=25cm
ditanya d...??
Ls=2×π×r×t
550=2×3,14×r×25
550=157r
r=550/157
r=3,5 cm
d=2×r
=2×3.5
=7
Tinggi = 25 cm (k=phi x d)
Ditanya = Diameter
Jawab :
L s = K . Tinggi
550 = phi.d . 25
22=phi.d
22= 22/7
d=7 => Jawaban = B
