The area (A) for a circle of radius r can be calculated as
\n" ); document.write( "\"A+=+pi+r%5E2\"
\n" ); document.write( "To help students remember that formula, teachers say
\n" ); document.write( "\"Apple pi(es) R square\"
\n" ); document.write( "If the diameter is 16cm, the radius is 8cm, and the area is
\n" ); document.write( "\"A+=+pi+8%5E2=+201cm%5E2\"
\n" ); document.write( "
\n" );
