Sector area = (central angle / 360) * PI * radius^2
sector area = (72 / 360) * PI * radius^2
radius^2 = sector area / [(72 / 360) * PI]
radius^2 = 16.2 * PI / [(1 / 5) * PI]
radius^2 = 16.2 / .2
radius^2 = 81
radius = 9

It would be: 180/135 * 100 = 36/27 * 100
= 4/3 * 100
= 400/3 = 133.33
It means, 180 is 133.33% of 135. So, the difference would be: 133.33 - 100 = 33.33%
In short, Your Final Answer would be 33.33%
Hope this helps!
I'm assuming you mean (a-b)^2 : (a+b)^2
a^2 + b^2 cancel out leaving
-2ab versus +2ab
Therefore (a+b)^2 is +4ab greater.
