Answer :

Radius of the hemispherical tank = 1 m

= m ∴ Volume of water in the tank = π r

= × × × ×

= cu. m

= cu. cm

= × litres

Water emptied per second = 7 litres ∴ Time required to empty the tank = × ×

= 1604.17 seconds

=

= 26.74 minutes

= m ∴ Volume of water in the tank = π r

^{3}= × × × ×

= cu. m

= cu. cm

= × litres

Water emptied per second = 7 litres ∴ Time required to empty the tank = × ×

= 1604.17 seconds

=

= 26.74 minutes
