Marks: +1, -0

A cylindrical tank of diameter 35 cm is full of water. If 11 litres water is taken out from the tank, find the drop in the water level in the tank.
(Use π = 22/7)

9.425 cm
10.428 cm
11.428 cm
12.428 cm

Solution:

Here,

{22}/7 × ({35}/2)^2 × h

= 11 × 1000
∴ h =

{11×1000×2}/{11×5×35}

=

{80}/7

= 11.428 cm
