Question

Rain water, which falls on a flat rectangular surface of length 6cm and breath 4m is transferred into a cylindrical vessel of internal radius 10cm. What will be the height of water in the cylindrical vessel if a rainfall of 1cm has fallen____?

Answer 1

Given length of rectangular surface = 6cm

Breath of rectangular surface = 4cm

Height (h) = 1cm

Given radius of cylindrical vessel = 20cm

Let height off cylindrical vessel be  h₁

Since rains are transferred to cylindrical vessel.

So equating (1) with (2)

Therefore, height of water in cylindrical vessel = 190.9cms
