Pembahasan:
1. Jari-jari (r) = 7 cm
Tinggi = 19 cm
π = 22/7
Volume = π x r x r x t
Volume = 22/7 x 7 x 7 x 19
Volume = 2.926 cm³
Jadi, volume tabung tersebut 2.926 cm³
2. Diameter = 14 cm
Jari-jari (r) = Diameter : 2 = 14 : 2 = 7 cm
Tinggi = 21 cm
π = 22/7
Volume = π x r x r x t
Volume = 22/7 x 7 x 7 x 21
Volume = 3.234 cm³
Jadi, volume tabung tersebut 3.234 cm³
3. Jari-jari (r) = 10 cm
Tinggi = 18 cm
π = 3,14
Volume = π x r x r x t
Volume = 3,14 x 10 x 10 x 18
Volume = 5.652 cm³
Jadi, volume tabung tersebut 5.652 cm³
