Vol of water pumped out per second = 22/7 * (7/2)^2*72 cc
= 2772 cc
= 2.772 litre
Hence that per hour = 2.772 * 3600 = 9979.2 litre
= 2772 cc
= 2.772 litre
Hence that per hour = 2.772 * 3600 = 9979.2 litre

parul dosti todne me to tumne time hi ni lagaya
aisa hi usne kiya tha
aaj tumne kar diya
toddi dosti mujhse
shayad ladkiya hoti hi aisi h
main kabhi samajh hi ni ska
shayad tume smjhne lga tha
par tumne aankhen khol di
aisa q kiya
