You can put this solution on YOUR website!
Area of the concrete path is $\"pi%2A7.7%5E2-pi%2A7%5E2\"$ square meters, using 0.70 meter for 70 centimeters.
\n" ); document.write( "That area, $\"pi%287.7%5E2-7%5E2%29\"$
\n" ); document.write( " $\"pi%287.7-7%29%287.7%2B7%29\"$
\n" ); document.write( " $\"pi%2A%280.7%29%288.4%29\"$
\n" ); document.write( "area is 18.47 square meters. You can apply the price of concrete. \n" ); document.write( "
