For this case we must find the area of the cookie, knowing that it has a circular shape. By definition, the area of a circle is given by:
Where:
r: It is the radius of the circle
According to the data we have:
Thus, the area of the cookie is:
We have 
We round:
Thus, the area of the cookie is

Answer:
a.) 60
Step-by-step explanation:
Margin of Error formula = z × s/√n
z = z score of confidence interval
We are given z score of 99% = 2.58
s = Standard deviation = $36
Margin of Error= ± 12
n= unknown
= 12 = 2.58 × 36/√n
12 × √n = 92.88
√n = 92.88/12
√n = 7.74
Square both sides
(√n)² = 7.74²
n = 59.9076
Approximately n ≈ 60
Therefore, the required sample size = 60
