MATEMATIKA KELAS 9
BANGUN RUANG SISI LENGKUNG
1. Tabung
Tabung adalah bangun ruang sisi lengkung yang dibentuk oleh dua buah lingkaran identik yang sejajar dan sebuah persegi panjang yang mengelilingi kedua lingkaran tersebut. Tabung memiliki 3 sisi yakni 2 sisi datar dan 1 sisi lengkung.
Contohnya : Tong sampah, kaleng susu, lilin dan pipa.

MATEMATIKA KELAS 9
BANGUN RUANG SISI LENGKUNG
1. Tabung
Contoh :
Tabung di samping memiliki jari-jari r = 3 cm, dan tinggi 7 cm. maka luas permukaan dan volumenya adalah?
L = 2π r (r + t)
L = 2π x 3 ( 3 + 7)
L = 2π x 30
L = 60π
Jadi, luas permukaan tabung adalah 60π cm2 .
V = πr2 x t
V = π (3)2 x 7
V = 63π
Jadi, Volume tabung adalah 63π Cm3
