Question

A cylindrical tank with diameter 2m and height 5m is completely filled with kerosene. How many cans of capacity 10 litres can be filled with the kerosene from the tank?

Answer 1

Heya mate, Here is ur answer

Diameter of tank = 2 m

Radius =2/2

=1 m

Height of tank =5 m

Volume of tank= πr^2h

$= \frac{22}{7} \times 1 \times 1 \times 5$

$= \frac{110}{7} m {}^{3}$

We know that 1 m^3 = 1000 l

$so \: \frac{110}{7} {m}^{3} = 1000 \times \frac{110}{7} l$

$= 1000 \times 15.714$


$= 15714 \: l$

Capacity of 1 can = 10 l

Capacity of tank = 15714 l

So, number of can = Capacity of tank/Capacity of can

=15714/10

=1571.4

Or

=1571 cans
