a compact disc has an approximate radius of 2 3/8 inches. disregarding the small hole at the center of the CD, what is the approximate area of a CD?

Respuesta :

Answer:

The area of CD is 17.71 [tex]in^{2}[/tex]

Step-by-step explanation:

Radius of the disk = [tex]2\frac{3}{8}[/tex] = 2.375 in

Since CD is in shape of circle So area of the circle is given by

[tex]A = \pi r^{2}[/tex]

Put the value of radius in above equation we get

A = 3.14 × [tex]2.375^{2}[/tex]

A = 17.71 [tex]in^{2}[/tex]

Therefore the area of CD is 17.71 [tex]in^{2}[/tex]
