Question

The diameter and height of a cylindrical vessel are 42cm and 30cm respectively. How many litres of water can it hold?

Answer 1

☆Hello friend☆

If diameter of diameter is 42 cm
Then, radius=42 cm/2= 21 cm

$volume = \pi {r}^{2} h$

Volume = 22/7 × 21 cm×21 cm× 30 cm
Volume= 22× 3 cm×21 cm×30 cm
Volume= 41580 cm^3

Converting into m^3= 41580/1000000 m^3
= 0.04158 m^3

Now, 1 m^3= 1000 litres
Littes can be holded = 0.04158×1000
41.85 litres

Hope it helps
