Jawaban:
Jadi volume gabungan bangun tersebut adalah 4.340 cm³
Penjelasan dengan langkah-langkah:
Volume balok
V = p x l x t
V = 20 x 14 x 10
V = 200 x 14
V = 2.800 cm³
Volume ½ tabung
d = 14 cm
r = 14 : 2
r = 7 cm
t = 20 cm
V = ½ x π x r x r x t
V = ½ x 22/7 x 7 x 7 x 20
V = 154 x 10
V = 1.540 cm³
V gabung = 2.800 + 1.540
= 4.340 cm³
V1 :
= PLT
= (20(14(10)
= (20(140)
= 2.800 CM³
V2 :
D = 14/2 = 7 CM (R)
MAKA :
V = 1/2πR²T
= 1/2(22/7(7(7(20)
= 1/2(22/7(7(140)
= 1/2(22/7(980)
= 1/2(21.560/7)
= 1/2(3.080)
= 3.080/2
= 1.540 CM³
V.GAB :
= (2.800 + 1.540)CM³
= 4.340 CM³
