Question

in a hospital used water is collected in a cylindrical tank of diameter 2m and height 5m after recycling this water is used during at park of a sphere whose length is 25 metre metre and breadth is 20m. if the tank is filled completely then what will be the height of standing water used for irrigation park

Answer 1

• Answer: For the tank,      H=5m     R=1m For the park,   l=25m  b=20m   h=?(assuming that water is not absorbed by soil) Volume of water in the tank = Volume of water used for irrigation     πR^2H=lbh 22/7(1)(1)(5)=25(20)h 22/7(5)=500h 22/7(5)(1/500)=h h=22/7(1/100) h=3.14/100meters h=3.14/100(100cm)       (1m=100cm) h=3.14cm Therefore the height of standing water is 3.14cm

Answer 2

hope this helps you
