16. A circular swimming pool has a diameter of 1818m. The sides are 33m high and the depth of the water is 2.52.5m. How much work (in Joules) is required to pump all of the water over the side

Explanation:

Radius ( r ) = 9 m

Volume = πr²h

= 3.14 x 9² x 2.5

= 635.85 m³

mass m = 635.85 x 10³

height by which centre of mass is raised

= (33 - 2.5/2 )

= 31.75 m

work done

= mgh

=  635.85 x 10³x 9.8 x 31.75

= 197.84 x 10⁶J
