Question 1161410
The new height becomes  {{{14-6=8}}} inches.  Since you say nothing about any top surface or bottom surface, then surface area becomes  {{{14+2*pi*4=highlight(14+8pi)}}} square inches.


If you meant, the 6 inche strip is this value in LENGTH of the strip, then you still need to be given the WIDTH of the strip in order to find the cylinder new area.
