Question 1066766
{{{ A = pi*r*l }}}
where {{{ A }}} is the lateral surface area
{{{ l  }}} is the slant height
------------------------
{{{ l^2 = 30^2 + 50^2 }}}
{{{ l^2 = 900 + 2500 }}}
{{{ l^2 = 3400 }}}
{{{ l = sqrt( 3400 ) }}}
{{{ I = 58.3095 }}}
and
{{{ A = pi*30*58.3095 }}}
{{{ A = pi*1749.29 }}}
{{{ A = 5495.543 }}}
---------------------
For the overlap I think I need a strip
{{{ .5*58.3095 = 29.155 }}}
and
{{{ 5495.543 + 29.155 = 5524.698 }}}
Rounded off, this is {{{ 5525 }}} cm2
