Perhatikan baik², Jika tinggi tabung = diameter atau 2 x Jari²
Volume Bola : Volume Tabung
4/3πr³ : πr²t
4/3πr³ : 2πr³
4/3 : 2
1/3 : 2
2 : 3
Jadi, Volume Tabung = 3/2 x 150 = 225 cm³
No. 3) Jawabannya D
Volume baru = Volume lama x (pembesaran atau pengecilan jari jari)² x (pembesaran atau pengecilan tinggi)
Volume = 120 x 2² x 3/5 = 480 x 3/5 = 288 cm³
