Question

Rain water, which falls on a flat rectangular surface of length 11 metres and breadth 4 metres is transferred into a cylindrical vessel of internal radius 80 cm. What will the height of the water in the cylindrical vessel be if the rainfall is 2cm?​

Answer 1

Answer:43.78cm

Step-by-step explanation:l=1100cm

b=400cm

h=2cm

Volume of cuboid=l×b×h

=1100×400×2

=880000cubic cm

Volume of cylinder=22/7×r×h

=880000=22/7×80×80×h

By calculating,we get h=43.75
