Surface area in square units = pi*radius2
Pi*6 * * * * * Independent of the radius? Makes no difference if the disc is twice as wide? I think not! It is actually 2*pi*r2 where r is the radius of the disc.
Area of disc: pi*6^2 = 36*pi square cm
The area of a disc of radius R units is pi*r^2 square units.
It is the surface area of the two ends plus the surface area of the curved surface. Surface area of each end is pir2 Surface area of the curved surface is 2pirh Total surface area = 2pir2 + 2pirh
To obtain the ratio of surface area to volume, divide the surface area by the volume.

If r is the radius of the disc, then pi*r2 square units.

The area of a disc of radius R units is pi*r^2 square units.
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.
It is the surface area of the two ends plus the surface area of the curved surface. Surface area of each end is pir2 Surface area of the curved surface is 2pirh Total surface area = 2pir2 + 2pirh
The total surface area! The total surface area! The total surface area! The total surface area!
If a Mac computer is not accepting a disc, check the disc for surface scratches. Superficial scratches can compromise the disc and result in errors. You will also want to be sure that the disc is compatible with Mac computers.
It should be relatively easy to find the surface area of a box when you are given the surface area.
Yes, you can buff the surface of a disc with toothpaste to remove, or lessen, scratches.
