Height of capsule
= Height of cylinder + 2×radius of hemisphere
Height of cylinder
= Height of capsule - 2×radius of hemisphere
= 16 - 12 = 4cm
Therefore the total volume of the capsule
= volume of cylinder + 2×volume of hemisphere
Volume of cylinder = πr²h = 3.14 × 6² × 4 = 452.16cm³
2×Volume of hemisphere = 2 × ⅔πr³ = 4/3πr³
= 4/3 × 3.14 × 6³
= 904.32cm³
Therefore the total volume of the capsule
= volume of cylinder + 2×volume of hemisphere
= 452.16 + 904.32 = 1356.48cm³
