tolong dijawab yang benar volumenya.

1. diket : t=16 cm,d=12cm=r=6 cm
Vtb= pi r^2 t = 3,14×6^2×16 = 3,14×36×12 =1356,48 cm3

2. diket : t=18 cm,d=14cm=r=7 cm
Vtb= pi r^2 t = 22/7×7^2×18 = 22/7×49×18 = 2772 cm3
3. diket: t = 24 cm, d=18 cm=r=9cm, volume tabung= ?
jawab = Vtb = pi r^2 t = 3,14×9^2×24 = 3,14×81×24 = 6104,16 cm3
