Answer:

128.8cm^2

area of circle with radius 6cm = π6^2

area of circle with radius 9cm = π9^2

shaded region is equal to π9^2 - π6^2

Answer:

$9d = 36$

Step-by-step explanation:

See attachment for complete question

$Length = 36ft$

$n = 10$

From the question, we understand that one shrub must be at both ends.

Taking the first as a point of reference, we're left with:

$(n - 1) * distance = 36$

Substitute 10 for n and d for distance

$(10 - 1) * d = 36$

$9 * d = 36$

$9d = 36$

Hence:

$9d = 36$ answers the question
