Algebra.Com's Answer #670821 by addingup(3677)![]() ![]() You can put this solution on YOUR website! net of a solid shape with two PARALLEL congruent circular faces. The shape has a height of 25 and each circular face has a diameter of 7. \n" ); document.write( ": \n" ); document.write( "Diameter 7, radius = D/2 = 7/2 = 3.5 \n" ); document.write( "Height: 25 \n" ); document.write( "------------------------------- \n" ); document.write( "Area of the circle: \n" ); document.write( "Pir^2 = A \n" ); document.write( "Pi*3.5^2 = 38.48 this is the area of each of the circular faces, and we have 2 faces: 38.48*2 = 76.96 \n" ); document.write( "------------------- \n" ); document.write( ":Area of the cylinder: \n" ); document.write( "Perimeter of the faces: \n" ); document.write( "dPi = P \n" ); document.write( "7*Pi = 22 \n" ); document.write( "Area of the side: \n" ); document.write( "22*25 = 550 Now add the area of the faces: \n" ); document.write( "550+76.95 = 626.96 you may have to round off to 627\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
