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>

Answer:
Step-by-step explanation:
Amount by which the plant gre in one month = 9.5 - 8.75 = 0.75
Amount by which it will grow in x months = x * 0.75
The hegiht of the plant after 6 months = amount it will grow by in 6 months + current heigt = 0.75x + 8.75
Hence answer is
d
