CIRCUMFERANCE=2piR
\n" ); document.write( "28=2*3.14*R
\n" ); document.write( "28=6.28R
\n" ); document.write( "R=28/6.28
\n" ); document.write( "R=4.4586 THIS IS THE RADIUS.
\n" ); document.write( "SEEING AS THE DIAMETER IS TWICE THE RADIUS. WE MULTIPLY THE R BY 2 & WE GET
\n" ); document.write( "2*4.4586=8.9172 WHICH IS THE DIAMETER OF A CIRCLE WITH A CIRCUMFERANCE OF 28.
\n" ); document.write( "
