Hi everyone,

Could you please tell me if this is correct?

The hemispherical tank shown is full of water. Given that water weights 62.5 lb/ft^3 and the radius is 5ft, find the work required to pump water out of the tank.

weight=force=(3.14)(25 delta y ft^3)(62.5 lb/ft^3)

=(1562.5)(3.14)

distance=y (m)

work int. 0 to 10 (4908.7)ydy=

(245435ft)(pounds)

Thank you very much
