The circumference of a circle is about 31.4 meters. The radius of the circle is about what?
\n" ); document.write( ".
\n" ); document.write( "Since:
\n" ); document.write( "circumference = 2(pi)r
\n" ); document.write( "where
\n" ); document.write( "r is radius
\n" ); document.write( "pi is 3.14
\n" ); document.write( ".
\n" ); document.write( "31.4 = 2(3.14)r
\n" ); document.write( "15.7 = (3.14)r
\n" ); document.write( "5 meters = r \n" ); document.write( "
\n" );
