What is the volume of a standard CD

[From: ] [author: ] [Date: 11-05-04] [Hit: ]
A = Pi7.A = 56.V = Pi(3600 - 56.25) * 1.V = 3898.V ≈ 12246.......
i want the mathematical water volume, not disk capacity in case your wondering. thanks!

15mm Internal diameter, 120mm external diameter, 1.1 mm thick

A = Pir^2

A = Pi60^2
A = 3600Pi

A = Pi7.5^2
A = 56.25Pi

V = Pi(3600 - 56.25) * 1.1
V = 3898.125Pi mm^3

V ≈ 12246.32 mm^3
