$\"12000%2A%281+%2B+r%29%5E2+=+27000\"$
\n" ); document.write( " $\"%281%2Br%29%5E2=27000%2F12000\"$
\n" ); document.write( " $\"%281%2Br%29%5E2=27%2F12\"$
\n" ); document.write( "Now take the square root of both sides:
\n" ); document.write( " $\"%281%2Br%29=sqrt%2827%2F12%29\"$
\n" ); document.write( " $\"r=sqrt%2827%2F12%29-1\"$
\n" ); document.write( " $\"r=sqrt%28++%28+cross%283%29%2A3%2A3+%29+%2F+%28+cross%283%29%2A2%2A2%29++%29+-1+\"$
