0.493 = 0.000 + 0.400 + 0.090 + 0.003
It may be also written as: 0.493 = 0 + 0.4 + 0.09 + 0.003
1.222 = 1.000 + 0.200 + 0.020 + 0.002
It may be also written as: 1.222 = 1 + 0.2 + 0.02 + 0.002
2n + 8 ≤ 25 |subtract 8 from both sides
2n ≤ 17 |divide both sides by 2
<u>n ≤ 8.5</u>

Remark
You need 2 facts to solve this
1. The area of a hexagon is
A = 3*(sqrt(3) ) * a^2/2
Just to make this clear, I'll put it in Latex

2. The second fact you need to know is that the radius = the length of the side a.
Givens
r = 20 in
a = r where a is the length of the side of a hexagon.
Formula Substitute and solve.
A = 3*(sqrt(3) * a^2 ) / 2
A = 3*(sqrt(3) * 20^2) / 2
A = 3*sqrt(3) * 400 / 2
A = 3*sqrt(3) * 200
A = 3*1.7321 * 200
A = 1039 square inches.
