By wrapping the paper around the can, you would be making the
paper match the circumference of the can
If C = circumference
Let d = diameter
C+=+pi%2Ad
If wrapping the length of the paper around the can,
27.5+=+3.1416%2Ad
d+=+27.5+%2F+3.1416
d+=+8.75 cm
If wrapping the width of the paper around the can,
21.3+=+3.1416%2Ad
d+=+21.3+%2F+3.1416
d+=+6.78 cm
