The rain water collected from the roof just filled thecylindrical vessel, then find the rain fall in centimeter. Whatvalue of housing society is reflected in this question?
Answer» Vol. of rain water on roof = vol. of water in cylinder lbh =πr^2h 2220h= 22/711*3.5 h= 220.5/22*20 h=0.025m =2.5cm

Answer»

Vol. of rain water on roof = vol. of water in cylinder

lbh =πr^2h

22*20*h= 22/7*1*1**3.5

h= 22*0.5/22*20

h=0.025m =2.5cm
