Answer 2

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 :

$V=\pi r^2h$

r = radius of cylinder, r = 14 m

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

$V=\dfrac{22}{7}\times 14^2\times 7\\\\V=4312\ m^3$

Since,

1 m³ = 1000 L

or

1 m³ = 1 kL

So,

4312 m³ = 4312 kL

So, the cylinder can hold 4312 kL of water.
