the water passed from the pipe in 30 minutes is 7×30×60×area of the pipe
= 7×30×60×2pi ×4 cm3
now the if we divide the area of the tank's surface we'll get the water level
(7×30×60×8 pi)/(2pi×40)
=630cm
= 7×30×60×2pi ×4 cm3
now the if we divide the area of the tank's surface we'll get the water level
(7×30×60×8 pi)/(2pi×40)
=630cm
