Question

a tank in shape of a frustum having diamter of top and bottom are 6m and 10 m respectively.if the height is 3 m then how many litres of oil can be filled in it.how many drums 200 litre each can be filled​

Answer 1

Answer:

I don't know the answer

Answer 2

There are 77 drums needed, and 15400 liters of oil can be filled in it.

Step-by-step explanation:

Since we have given that

Diameter = 6 m

Radius = 3 m

Diameter = 10 m

Radius = 5 m

Height = 3 m

So, Volume of frustum would be

$\dfrac{\pi h}{3}(r_1^2+r_2^2+r_1r_2)\\\\=\dfrac{22\times 3}{7\times 3}{(3^2+5^2+3\times 5)}\\\\=\dfrac{22}{7}(9+25+15)\\\\=\dfrac{22}{7}(49)\\\\=22\times 7\\\\=154\ m^3$

As we know that

1000 l  = 1 m³

154 m³ = 15400 l

So, if capacity of each drum = 200 l

So, Number of drums required would be

$\dfrac{15400}{200}=77$

Hence, there are 77 drums needed, and 15400 liters of oil can be filled in it.
