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( "
\n" );
