Question

154 litres of water are poured into an upright cylindrical tank of radius 7m find height of water tank in cm​

Answer 1

sorry but I don't know the answer

Answer 2

Answer:

0.1 cm

Step-by-step explanation:

Given :-

Capacity (Volume) of cylindrical tank = 154 l

Radius of tank = 7 m

To find :-

Height of tank in cm

Solution :-

Let the height of the tank be 'x'.

Volume of tank in cm :-

As 1 litre = 1000 cm³

So, 154 litre = 154 * 1000

                    = 154000 cm³

Radius in cm = 7 * 100

                      = 700 cm

Volume of cylinder = π*r²*h

154000 = 22/7 * 700² * x

154000 = 22/7 * 700 * 700 * x

154000 = 22 * 100 * 700 * x

154000 = 2200 * 700 * x

154000 = 1540000 * x

154000/1540000 = x

1/10 = x

OR

x = 0.1 cm

Hence, the height of the cylindrical tank is 0.1 cm.
