Surface Area of a Cylinder:\r
\n" ); document.write( "\n" ); document.write( "\"S%5Ba%5D+=+2pi%2Ar%5E2+%2B+2pi%2Ar%2Ah\" \r
\n" ); document.write( "\n" ); document.write( "if the radius and height a cylinder is doubled\r
\n" ); document.write( "\n" ); document.write( "\"S%5Ba%5D+=+2pi%2A%282r%29%5E2+%2B+2pi%2A2r%2A2h\" \r
\n" ); document.write( "\n" ); document.write( "\"S%5Ba%5D+=+2pi%2A4r%5E2+%2B+2pi%2A4r%2Ah\" \r
\n" ); document.write( "\n" ); document.write( "\"S%5Ba%5D+=+4%282pi%2Ar%5E2+%2B+2pi%2Ar%2Ah%29\" ------quadrupled \r
\n" ); document.write( "\n" ); document.write( "surface area \"S\"' = \"4S%5Ba%5D\", so it increases by \"4\" times its original
