Hi there,,
\n" ); document.write( "Considering cylinder of 8\" height.
\n" ); document.write( "It will have a circumference of 5\"
\n" ); document.write( "To find radius:
\n" ); document.write( "Circumference = 2πradius
\n" ); document.write( "2πradius = 5\"
\n" ); document.write( "πradius = 2.5\"
\n" ); document.write( "Radius = 2.5\"/π\r
\n" ); document.write( "\n" ); document.write( "Volume = πr^2h
\n" ); document.write( "Volume = π(2.5/π)^2 x 8
\n" ); document.write( "Volume = 15.91 ins^3
\n" ); document.write( "........................
