The radius is 1/2 the diameter
\n" ); document.write( "given:
\n" ); document.write( "diameter = \"1.3%2A10%5E%28-12%29\"
\n" ); document.write( "radius = \".5%2A1.3%2A10%5E%28-12%29+=+.65%2A10%5E%28-12%29\"
\n" ); document.write( "radius = \"6.5%2A10%5E%28-13%29\" answer
\n" ); document.write( "This is now in \"scientific notation\"
\n" ); document.write( "Notice that I increased \".65\" by a factor of \"10\",
\n" ); document.write( "so I had to decrease \"10%5E%28-12%29\" by a factor of \"10\"
\n" ); document.write( "
\n" );
