What is the surface area of disc for both side of disc surface?
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.
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
What is the raised area or bump on the surface of a CD?
The raised area or bump on the surface of a CD is known as a "pits" and "lands" structure. These microscopic indentations (pits) and flat areas (lands) encode the digital information of the disc. When a CD player reads the disc, a laser scans these variations in height, translating them into audio or data signals. This encoding method is fundamental to how CDs store and retrieve information.
What is the formula for the area of a disc?
The area of a disc of radius R units is pi*r^2 square units.
What is the surfqace area of a cylinder?
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

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.
What is the surface area of circular disk?
If r is the radius of the disc, then pi*r2 square units.
How might you alter the shape of a spherical cell to increase its surface area?
One way to increase the surface area of a spherical cell is by forming microvilli on its surface. Microvilli are tiny finger-like projections that extend from the cell membrane, increasing the surface area for absorption or secretion. Another way is to flatten the cell to form a disc-like structure, which would also increase the surface area relative to a sphere.
What is the area from z disc to z disc?

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.
What are recessed areas on the surface of an optical disc?
PITS
Why red blood have larger surface area?
Red blood cells have a larger surface area relative to their volume due to their unique biconcave disc shape. This design increases the surface area available for gas exchange, allowing for more efficient uptake of oxygen and release of carbon dioxide. The increased surface area also facilitates the movement of red blood cells through narrow capillaries, enhancing their ability to deliver oxygen throughout the body.
Why isn't the Mac accepting the disc?
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.
Why are red blood cells disc shape?
To optimise the surface area available for the bonding of oxygen and haemoglobin, to form oxyhaemaglobin. Individuals with sickle cell anaemia, i.e. those with red blood cells which are not disk shaped have a reduced capacity to carry oxygen in their blood.
