Question 26

A cylindrical vessel of radius 3.5 m is full of water. If 15400 litres of water is taken out from it, then the drop in the water level in the vessel will be:

Solution

Volume of water = 15400 litres = 15400000 ml
radius(r) = 3.5 m = 350 cm
ATQ,
$$\pi r^2 h = 15400000$$
$$\frac{22}{7} \times 350 \times 350 \times h = 15400000$$
h = 15400000/385000 = 40 cm
