Question

Please give answer pleaseeeee

Answer 1

Radius of tank=10/2=5m

Height of tank=2m

Vol of tank=πr^2h

=22/7*(5)^2*2

=157.14 m^3 (approx.)

Radius of pipe =20cm/2

=10cm=0.01m

Height of pipe = 3km/hr =3000m/60sec

=300/6

Vol of pipe=22/7*(0.01)^2*300/6

=0.015714 m^3

Time taken= 157.14/0.015714

=166 min (approx.)
