If the diameter of a circle is:
\n" ); document.write( "1.3 • 10^-12 meters, then what is its radius?
\n" ); document.write( "---------------------
\n" ); document.write( "r = half of d
\n" ); document.write( "r = 1.3 • 10^-12 meters = 0.65*10^-12 m
\n" ); document.write( "r = 6.5*10^-13 meters
\n" ); document.write( "
\n" ); document.write( "
\n" );
