Algebra.Com's Answer #677853 by addingup(3677)![]() ![]() You can put this solution on YOUR website! perimeter for your window is 2w+2h+πr (normally the circumference would be π2r but here we have only one-half of the circumference). \n" ); document.write( "----------------------------------------------- \n" ); document.write( "2(2)+2(1) = 6 this is the perimeter of the rectangle. \n" ); document.write( "The semi circle on top of the rectangle: \n" ); document.write( "Width of window: 2 this is the diameter of your semicircle. The radius is one-half: 2/2 = 1 \n" ); document.write( "π*1 = perimeter of the half circle = 3.14 \n" ); document.write( "Total perimeter: \n" ); document.write( "6+3.14 = 9.14 \n" ); document.write( " \n" ); document.write( " |
