volume of cylinder = pir^2h\r
\n" ); document.write( "\n" ); document.write( "= pi*20*20*12\r
\n" ); document.write( "\n" ); document.write( "= 15079.64 cu. inches\r
\n" ); document.write( "\n" ); document.write( "surface area of cylinder = 2pirh\r
\n" ); document.write( "\n" ); document.write( "=2*pi*20*12
\n" ); document.write( "=1507.96 sq. inches
