Question

10. The rain falls 10cm on a particular day. The rain
water that falls on
a roof 70 m long and 44 m
wide was collected in a cylindrical tank of radius
14 m. a. volume of water that on the roof.b.rise of water level in the take due to rain water. ​

Answer 1

Answer:

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

So, volume of water on roof = Ibh =

70x44x0.1=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=r2h3227x142h3D616h

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

So 308= 616h

h= 308/616=0.5 m
