14" cylinder w 5" in diameter ends. Measurement to cover cylinder w fabric

Question

I am making a neck roll pillow, which is a cylinder, but I can't figure out the measurement to cover the cylinder and the size of the circles to cover both ends.

Answer 1

me ges yu want the surfus area av cylinder

leng=14 & diam=5

The long thang become rektangel with leng=14 & wide=5pi

area=5pi*leng=5*3.141592654*14

=219.911755 or bout 220

then yu hav 2 end peeses...2*pi*rad^2

radius=5/2, rad^2=25/4, so end area=(25/2)pi=12.5pi

=39.26990813, or bout 39
