From a tap of inner radius 0.75 cm, water flows atr the rate of 7 m per second. Find the volume in litres of water delivered by the pipe in one hour.

Given,

Inner radius of tap = 0.75 cm

Rate of flow of water through tap = 7 m/s = 700cm/s

Volume of water delivered in 1 second = πr²h =

Volume of water delivered in 1 hour (60×60 sec) =

=
