Base area=pi*r^2
\n" ); document.write( "Base=3.14*2^2
\n" ); document.write( "Base=3.14*4
\n" ); document.write( "Base=12.56 ft^2
\n" ); document.write( "Volume= base*height
\n" ); document.write( "V=12.56*5
\n" ); document.write( "V=62.8 ft^3
\n" ); document.write( "1/165=62.5/x
\n" ); document.write( "x=165*62.5
\n" ); document.write( "x=10,362 lbs. is the weight of the cylinder.
