Suppose the diameter of the disk is D cm so that the radius is D/2 = R cm.
Suppose the diameter of the hole is d cm so that its radius is d/2 = r cm.
Then the area of one side of te disc is
pi*(R^2 - r^2)
Therefore the total area of the two sides is 2*pi*(R^2 - r^2) square cm.
This ignores the surface area of the edge which, although small, is not 0.

∙ 8y agoYou measure its outer diameter, divide by 2 to give the outer radius = R units.You measure its inner diameter, divide by 2 to give the inner radius = r units [radius of the hole].
Then area of the annulus = pi*(R^2 - r^2) square units.

The distance from the center of the compact disc to the edge of the disc is 6 centimeters what is the area of the compact disc?
Area is calculated using the value of pi times the square of the radius. Therefore, the area of a standard compact disc is 113.0976 square centimeters.
