Best Answer

The outer radius, R = 60 mm and the radius of the hole, r = 7 mm so the surface area is pi*(R^2 - r^2) = 11156 mm^2 = 111.56 cm^2. However, not all this area is used for data since there are blank bands at both ends.

The area utilised has R = 57.5 mm and r = 11 mm so that this area is 10007 mm^2 = 100.07 cm^2.
