You can put this solution on YOUR website!
Let $\"+C+\"$ = circumference
\n" ); document.write( " $\"+C+=+2%2Api%2Ar+\"$
\n" ); document.write( "You are given that:
\n" ); document.write( " $\"+pi%2F2+=+2%2Api%2Ar+\"$
\n" ); document.write( "Divide both sides by $\"+pi+\"$
\n" ); document.write( " $\"+1%2F2+=+2r+\"$
\n" ); document.write( " $\"+r+=+1%2F4+\"$
\n" ); document.write( "------------
\n" ); document.write( "Let $\"+A+\"$ = area of the circle
\n" ); document.write( " $\"+A+=+pi%2Ar%5E2+\"$
\n" ); document.write( " $\"+A+=+pi%2A%28+1%2F4+%29%5E2+\"$
\n" ); document.write( " $\"+A+=+pi%2F16+\"$ \n" ); document.write( "

\n" );
