Question

A cylindrical water tank is 2.1m long and its radius is 1m.Find the quantity of water in litres that can be stored in the tank

Answer 1

Answer:

Step-by-step explanation:

Given: r = 1m

h= 2.1m

Volume of the

cylindrical tank = pi r2 h

= 22/7 × 1×1×2.1

= 22×1×1×0.3

= 6.6m sq

Therefore, the quantity

of water in litres = 6.6 × 1000

= 6,600l

Answer 2

Answer:

Water tank can hold 6600 liters of water.

Step-by-step explanation:

A cylindrical water tank is 2.1m long and its radius is 1m.Find the quantity of water in litres that can be stored in the tank.

Volume of cylinder

$\boxed{\bold{Volume\:of\:cylinder= \pi \: {r}^{2} h \: {unit}^{3} }}$

here

$h = 2.1 \: m \\ r = 1 \: m$

Volume of water tank

$= \frac{22}{7} \times ( {1)}^{2} \times 2.1 \\ \\ = 22 \times 0.3 \\ \\ = 6.6 \: {m}^{3}$

we know that

$1 \: {m}^{3} = 1000 \: litres \\ \\ so \\ \\ 6.6 \: {m}^{3} = 6.6 \times 1000 \\ \\ = 6600 \: litres$

So, water tank can hold 6600 liters of water.
