Question

The rain water from a roof of 22m x 20m drains into cylindrical vessel having diameter of base 2m and height 3.5 m. If the vessel is just full. Then rain fall in (cm) is.

Answer 1

Answer:

volume of roof = volume of Cylindrical tank

l × b × h = π r² h

22×20×h = 22/7 (1)² × 3.5

On solving the value of h comes out to be,

h = 1/40 m

or h = 2.5 cm

so the rainfall in cm is 2.5 cm.
