A punching machine is used to punch a circular hole of diameter two units from a square sheet of aluminium of width 2 units, as shown below. The hole is punched such that the circular hole touches one corner P of the square sheet and the diameter of the hole originating at P is in line with a diagonal of the square.


The proportion of the sheet area that remains after punching is



A (π + 2)/8

B (6 – π)/8

C (4 – π)/4

D (π – 2)/4

E (14 – 3 π)/6
