1)A gasoline storage tank in the shape of a right circular cylinder with height 8m and radius 2m is completely filled with gasoline. How much work is required to pump all the gasoline out the top of the tank? The density of the gasoline is =735kg/m3 and g=9.8m/s2.

(Use decimal notation. Give your answer to the nearest whole number.)

2)A full water tank in the shape of a hemispherical bowl of radius 5m.

How much work is required to pump all the water to a height of 4m above the tank? (The density of water is 1000kg/m3).

(Use symbolic notation and fractions where needed.)

3)A swimming pool is in the shape of a rectangular parallelepiped 8ft8ft deep, 35ft long, and 23ft wide. It is filled with water to a depth of 7ft. How much work is required to pump all the water over the top? The weight of water per cubic foot is =62.43lb/ft3

(Round your answer to the nearest wholenumber.)

4)A gasoline storage tank in the shape of a right circular cylinder with height 11m and radius 2m is completely filled with gasoline. How much work is required to pump all the gasoline out the top of the tank? The density of the gasoline is =740kg/m3 and g=9.8m/s2.
