The outside circle of the drive has a diameter of 100 meters and the drive has a uniform width of 12 meters. Which of the following is closest to the area, in square meters, of the garden? \n" ); document.write( "------------ \n" ); document.write( "Subtract 12 from the radius, not from the diameter. \n" ); document.write( "---- \n" ); document.write( "Inside area = pi*r^2 \n" ); document.write( "r = 50-12 = 38 m \n" ); document.write( "Area = 1444pi = 4536 sq meters. \n" ); document.write( "======================\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
