Question

estimate the capacity in litres of a cylindrical drum which is 45 cm in diameter and 66 cm high

Answer 1

Step-by-step explanation:

give that

d = 45 cm, h = 66 cm

$cylinder \: capacity(v) = \pi {r}^{2} h$

r = d/2 = 45/2 cm

V = (22/7) × (45/2)² × 66

V = 105010.714 cm³

$we \: know \: \\ 1000 {cm}^{3} \: = 1 \: litre$

V = 105010.714 × 1/1000 litre

V = 105.01 litre
