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.

The distance from the center of a compact disc to the edge of the disc is 6 centimeters. What is the area of the compact disc?
Area of disc: pi*6^2 = 36*pi square cm
A compact disc to the edge of the disc is 6 centimeters What is the area of the compact disc?
A = pi * r^2 A = pi * 6^2 A = 36pi If you are using 3.14 for pi, then ANS : D.) 113.04 cm^2

The distance from the center of a compact disc to the edge of the disc is 6 centimeters. What is the area of the compact disc?
Area of disc: pi*6^2 = 36*pi square cm
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.
