If the diameter of a circle 1.3 X 10^-12 meters, then what is its radius?
\n" ); document.write( "-------------------
\n" ); document.write( "radius = (1.3 X 10^-12 1.3 X 10^-12)/2
\n" ); document.write( "= 0.65x10^-12
\n" ); document.write( "Now multiply the 0.65 by 10 and divide the 10^-12 by 10 to get
\n" ); document.write( "= 6.5x10^-13
\n" ); document.write( "----------------
