Answer: 12.56 (insert units)
Step-by-step explanation:
radius = 2
so pi x r^2 = 3.14 x 2^2 = 12.56
(Units were not mentioned)
We know that the diameter of the inner circle (d) and the side of a regular octagon (s) are tied by the formula:
d = (1 +√2) × s
The inverse formula is:
s = d / <span>(1 +√2)
Plugging in numbers:
s = 7 (1 + </span>√2)
= 2.9 ft
Therefore the correct answer is A) <span>2.9 feet</span>
The domain should be all Natural numbers
(4x - 1)2 = 11
(4x - 1) = 22
4x - 1 = 22
4x = 23
x = 5.75
