Question

Water tank is cylindrical in shape. the diameter of its base on the inside is 28 m and its depth is 7 m. how many kilolitres of water can it hold?

Answer 1

Given that,

The diameter of the base of a cylinder is 28 m

Its height is 7 m

To find,

The volume of water in kilolitres.

Solution,

The volume of a cylinder is given by the formula as follows :

V=\pi

${r}^{2}h$

r = radius of cylinder, r = 14 m

Putting all the values in the above formula, we get:

V=

$\frac{22}{7} \times {14}^{2} \times 7$

V=

${4312}^{3}$Since,

1 m³ = 1000 L

or

1 m³ = 1 kL

So,

4312 m³ = 4312 kL

So, the cylinder can hold 4312 kL of water.
