Answer:
Choice C correct answer.
Step-by-step explanation:
From the question statement, we observe that
d=6 in
r=d/2
so, r=6/2=3 in
The formula to find area is
A = πr²
Putting the value of radius, we get
A = π(3)²
A= 9π in²
106,127,129,132,135,138,140,158
132 + 135 = 267
267/2 = 133.5
Median is 133.5

The answer is given by the
second choice: letter B. 14.75 is the answer because to get the mean, you
should add all the numbers and then divide it by how many numbers there are.
For example, in this case, you add 12, 17, 16, 10, 20, 13, 14, 14, 12, 12, 19,
18 to each other. You will get the answer 172. After that, you should
divide 172 by 12 because there are 12 numbers in the data set.
