Answer :

Given: Height of cylindrical tank = H = 5 m

Diameter of cylindrical tank = d = 2 m


Radius of cylindrical tank = r = d/2 = 1 m


Volume of cylindrical tank = πr2H = π × (1)2 × 5 = 5π m3


Length of park = l =25 m


Breadth of park = b = 20 m


Let height of the park = h m


Volume of water in park = lbh = 25 × 20 × h = 500h m3


Now, volume of water in tank is equal to volume of water in the park.


5π = 500h


π = 100h


3.14 = 100h


h = 0.0314 m


Height of water in park = 0.0314 m


Recycling of water helps in conserving water resources and reduces wastage of water.
