<PRE><B>Question 37143</B>
I am guesing that the solid formed is a cylinder.  The volume of a cylinder can be found from the formula V = area of the end (a circle) times the height of the cylinder.


V = area x height
V = (pi x r^2)(12.8)
V = (3.14 x 49)(12.8)
V = 1,969.4 cubic inches


I hope that is right?</PRE>
