Algebra.Com's Answer #482131 by Alan3354(69443) You can put this solution on YOUR website! The height of the cone is 6 cm. The angle at the vertex of its axial section is . Find the surface area of the cone. \n" ); document.write( "-------------- \n" ); document.write( "2A = angle \n" ); document.write( "Slant height = 6/cos(A) = 6sec(A) \n" ); document.write( "Lateral area = pi*SH = 6pi*sec(A) \n" ); document.write( "Area of base = pi*r^2 = 9*pi \n" ); document.write( " \n" ); document.write( " |
