Question

A hemispherical tank has inner diameter 4.2 rn. Find its capacity in litres.

Answer 1

Answer:

Capacity of tank:19404 litres

Step-by-step explanation:

Volume of Hemisphere tank

$\boxed{V = \frac{2}{3} \pi {r}^{3} }$

r= 2.1 m

Volume

$= \frac{2}{3} \times \frac{22}{7} \times 2.1 \times 2.1 \times 2.1 \\ \\ = 44 \times 0.3 \times 0.7 \times 2.1 \\ \\ = 19.404 \: {m}^{3}$

Capacity of tank in litres:

As

$1 {m}^{3} = 1000 \: litres$

So,

$= 19.404 \times 1000 \\ \\ = 19404\: litres$

Hope it helps you.
