Question 744848: If the diameter of the compact disc is 120 millimeters, what is the approximate area ignoring the center hole? (Use 3.14 for .) Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Area of a circle = pi r^2
Radius of disc = 60 mm. (120 mm/2)
Area = pi x 60^2
Area = 3.14 x 6062
Area = 11304 mm^2
