Question

the rainfall 10 cm on a particular day the rain water that falls on a roof 70 metre long and 44 m wide was collected in a cylinder tank of radius 14 metre​

Answer 1

Answer:

(a) l=70; b= 44m and h= 10 cm = 0.1 m

So, volume of water on roof = lbh = 70×44×0.1=308m3 (As, the rainwater will form a cuboidal shaped solid on the roof)

(b) Let h be the height of the water in the tank.

Volume of the water in tank=πr2h=227×142h=616h

As, the water is falling to the tank from the roof,

So 308= 616h

h= 308/616=0.5 m
