Question

A tank of cylindrical shape has radius 2.8 m and its height 3.5 m. Complete the activity to find how many litres of water the tank will contain.

Answer 1

Solutions :-

Given :
Radius of cylindrical tank = r = 2.8 m
Height = h = 3.5 m


Find the volume of cylindrical tank :-

Volume = πr²h
= 22/7 × (2.8)² × 3.5 m³
= 22/7 × 7.84 × 3.5 m³
= 86.24 m³


We know that,
1 m³ = 1000 litres
86.24 m³ = 1000 × 86.24 = 86240 litres


Hence,
86240 litres of water the tank will contain.

Answer 2

$\huge\boxed{\texttt{\fcolorbox{red}{aqua}{Solution ;}}}$

Given that :-
r = 2.8 m
h = 3.5 m

So the value of the cylinder =>
We know the formula i.e. pi r^2 h
So , let's get started with it :-

$= 22 \div 7 \times (2.8) { }^{2} \times 3.5m ^{3}$

$= 22 \div 7 \times 7.84 \times 3.5m ^{3}$

$= 86.24 \: m ^{3}$

We are well known with it that :-

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

So :-

$86.24 \: m^{3} = 1000 \times 86.24 = 86240 \: litres$

So , 86240 litres of water can be contained by the Tank.
