Answer:
D 81 pi units^2
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
18 pi = 2 * pi *r
Divide each side by 2 * pi
18 pi / (2 pi) = 2 pi * r/ (2 pi)
9 = r
Now we can find the area. Area is given by
A = pi r^2
A = pi * 9^2
A = 81 pi units^2
Answer:

Step-by-step explanation:
The mean of a data us the addition of all numbers in the data set and then dividing them by the number of values in a set.
<h3>What is a mean?</h3>
Your information is incomplete. Therefore, an overview will be given. It should be noted that a mean simply means the average of a set of numbers that are given.
For example, if we have the following numbers:
3, 9, 4, 1, and 3. The mean will be:
= (3 + 9 + 4 + 1 + 3)/5
= 4
The mean absolute deviation is the average distance between the data points and the mean.
