The rain water from a roof af dimensions ` 22 m xx 20 m ` drains into a cylindrical vessel having diameter of bases 2 m and height 3.5 m. If the rain water collected form the roof just fill the cylindrica vessl, them find the rainfull (in cm).

Text Solution

Verified by Experts

The correct Answer is:
395.37 kg
Let total rain =h metre
Volume of rain water on the roof =`22xx20xxh m^(3)`
Radius of cylindrical vessel `'r'=(2)/(2)=1m`
Height 'H' =3.5
Volume of vessel =`pir^(2)H=(22)/(7)xx1xx1xx3.5=11m^(3)`
`22xx20xxh-11`
`h=(11)/(22xx20)`m
`h=(11xx100)/(22xx20)cm=2.5 cm`
