For this case we must divide the following expression:

The expression can not be simplified. When dividing we have that its decimal form is given by:
3,201550
If we convert to a mixed number we have:

Verifying:

Answer:

Add 5x + 5 and that is the bottom of it and the top stays 1
An 8 sided polygon is, an Octagon
Area of a circle is found using the formula: Area = π * r^2
Using 3.14 for π
Area of the bull'e eye = π * 2^2 = 4π = 4 * 3.14 = 12.56 square inches.
This is 20% of the entire target.
To find the area of the entire target, divide the area of the bull's eye by the percentage:
Area = 12.56 / 0.20 = 62.8 square inches.
Round the answer as needed.
