A:
All right, so the first step would be to find the area of both the center and the whole.
The formula for area of a circle would be [tex]A= \pi r^2[/tex]
The radius of the whole would be 17.5 in, and the radius of the center would be 3.5 in. Let's plug them in.
To find the percentage, you would just have to find the fraction and turn it into a percent. [tex]38.48/962.11=0.04[/tex] That's 4/100, so it would be 4%.
