The rain falls 10cm on a particular day. The rain water that fals on a roof 70m long and 44m wide was collected in a cylindrical tank of radius 14m, find:- (a) Volume of the that falls on the roof. (b)Rise of water level in the tank due to rain water

volume of that fall on the roof=70x44x (0.1)=308m^3
volume of tank water=volume of fall water on the roof
pi.(14)^2.h=308
h=308/44x14
=1/2m
volume of tank water=volume of fall water on the roof
pi.(14)^2.h=308
h=308/44x14
=1/2m

kyonki ghanab ka volume length*breath *height hota hai
kya ab samajh main aaya
yes but 10 k 0.1 kaise hua
kyonki 10cm diya hai lekin chahiye meter main isiliye 10 ko 100 se divide kiye
ab agar samajh gaye to please ise brainliest answer banao
please take it brainliest
please akash
haa m ab samaj gayi pr mujhe brainliest ans banana nahi ata h....
koi baat nahi kosis karo ager ho jay to thik nahi ho to koi baat nahi
ok thanks I always ready for your next question

Rain falls = 10 cm = 0.1 m
Length of roof = 70 m
Breadth of roof =44 m
Volume of water falls on the roof = L × B × H
= 70 × 44 × 0.1
= 308 cu m
Radius of water tank = 14 m
Volume of water in tank = pie r square h
308 cu m = 22/7 × 14 × 14 × h
h = 308/22×2×14
h=1/2
Hence, height = 1/2 m
Length of roof = 70 m
Breadth of roof =44 m
Volume of water falls on the roof = L × B × H
= 70 × 44 × 0.1
= 308 cu m
Radius of water tank = 14 m
Volume of water in tank = pie r square h
308 cu m = 22/7 × 14 × 14 × h
h = 308/22×2×14
h=1/2
Hence, height = 1/2 m
