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.
radius. Therefore, the area of a standard compact disc is 113.0976
square centimeters.
The formula for the area of a circle is [tex] A=\pi r x^{2} [/tex]
The radius if half your diameter,
In this case your diameter is 12 so your radius is 6
Then you plug it in the equation, so it is A= [tex] \pi 6^{2} [/tex] or A=36 [tex] \pi [/tex]
This leaves you with the area at about 113.04 [tex]centimeters ^{2} [/tex]
