Awater tank is in the shape of a right circular cone with height 18 ft and radius 12 ft at the top. if it is filled with water to a depth of 15 ft, find the work done in pumping all of the water over the top of the tank. recall that the density of water is δ=62.4 lb/ft3.

661284 lb-ft

Explanation:

We are given that height of water tank=18 ft

Radius of circular tank=12 ft

Density of water=

We have to find the work done in pumping all of the water over the top of the tank.

Hence, the work done in pumping all of the water over the top of the tank=661284 ft lb.
