<PRE><B>Question 422601</B>
Since the base of the pool is a circle with diameter 12 feet, its shape is a cylinder with radius 6 feet. As we know the volume of cylinder is given by the formula.
         {{{ V = (Pi)*R^2*H }}} where H = 4 feet is the height of cylinder.

         {{{ V = (3.14)*(6)^2*(4) }}}

            V = 452.16 cubic feet.

Answer:To fill this pool we need 452.16 cubic feet water.
