You can put this solution on YOUR website!
the formula for the area of a square is A = pi * r^2\r
\n" ); document.write( "\n" ); document.write( "72 = pi * r^2\r
\n" ); document.write( "\n" ); document.write( "pi = 3.14 or 22/7
\n" ); document.write( "or use a calcuator and press the pi button\r
\n" ); document.write( "\n" ); document.write( "72 = pi * r^2
\n" ); document.write( "22.9183 = r^2
\n" ); document.write( "4.7873 = r
\n" ); document.write( "r = 4.79 cm
\n" ); document.write( "
