volume bangun diatas adalah...

diameter = 30 cm maka jari-jari = 15 cm
tinggi = 40 cm
volume = luas alas × tinggi
volume = (3,14 × 15 cm × 15 cm) × 40 cm
volume = 706,5 cm2 × 40 cm
volume = 28.260 cm3

diameter=30 cm
jari jari =30 cm ÷ 2
=15 cm

volume= pi × r × r × t
=3,14 × 15 cm × 15 cm × 40 cm
= 28.260 cm³
