Question

in a hospital used water is collected in a cylindrical tank of diameter 2 metre and height 5 metre after recycling this water is used to irrigate a Park of hospital whose length is 25 m and breadth is 20 m if a tank is filled completely then what will be height of the standing Water used for irrigating the park writeyour views on recycling of water

Answer 1

Diameter of cylinder (d) = 2 m
Radius of cylinder (r) = 1 m
Height of cylinder (H) = 5 m
Volume of cylindrical tank, Vc = πr2H = π×(1)2×5=5π m
Length of the park (l) = 25 m
Breadth of park (b) = 20 m
the height of standing water in the park = h Volume of water in the park = lbh = 25×20×h
Now water from the tank is used to irrigate the park.
So, Volume of cylindrical tank =
Volume of water in the park
⇒5π=25×20×h⇒
5π/25×20=h⇒
h=π/100 m⇒
h=0.0314 m

Hope it helps!!!
