Formular for volume of cylinder = πr²h
Formular for volume of Hemi-Sphere = ⅔πr³
Volume of Large Cylinder
= π(0.625)²(0.7)
≈ 0.859 m³ (3s.f.)
Volume of Small Cylinder
= π(0.375)²(0.8)
≈ 0.353 m³ (3s.f.)
Volume of Hemi-Sphere
= ⅔π(1.5)³
≈ 7.07 m³ (3s.f.)
Volume of water
= 7.07 - 0.859 - 0.353
≈ 5.85 m³ (nearest tenth)
