Answer:
163.3m²
Step-by-step explanation:
area = Pi(r²)
r = d / 2
r = 12
12² = 144
144 x 3.14 = 452.16
diameter of bigger circle = 24 + 4 (2 on each side)
28 / 2 = 14
14² = 196
196 x 3.14 = 615.44
sidewalk = bigger - smaller
sidewalk = 615.44 - 452.16
sidewalk = 163.3
Three million three hundred eighty eight thousand one hundred ninety eight.

Answer:
The answer is 0.1935
Step-by-step explanation:
Solution
From the question given, we will find the probability that a randomly selected azalea has no fragrance or is not colored
Now,
p (Fragrance, not colored)
Thus,
p (Fragrance, not colored)/ p (Not colored)
so,
12/62 = 0.1935
Note: Kindly find an attached copy of the complete question and the inputted values.
If the area of the old garden was 1m^2, then the side lengths were both 1
if she increases the lengths by 50%, then 1 turns into 1.5
1.5 times 1.5 is 2.25
The area of her new garden is 2.25m^2
