We will use formula for circumference of circle:
lets name it as O
O = 2*r * pi
when we express r in this formula we get:
O = 2*2.2*pi
O = 4.4*pi
From this we can see that for given radius, answer is 4.4. The formula only depends on pi and that is what "in terms of pi" means.
Answer:

Answer:
2.86
Step-by-step explanation:
Add all of them together to get 20, divide by the total employees so 7, you get 2.857. Round to nearest hundredth to get 2.86
Answer:
Scatter plot
Step-by-step explanation:
Using a scatter plot will allow the sales manager to show the data collected about the number of customers who enter the store and the dollar volume of sales for each day because the plot will have a dot to represent each day. The analyze of the pattern formed by the dots will show if there is a relation between the variables and what kind of relation is (systematic or causal). She can also add a regression line to find an explanation for the relation between the variables.
Answer:
A) all real numbers greater than or equal to 2
Domain: 
Step-by-step explanation:
The variable in the radical <em>x </em>cannot be less than 0 as that wouldn’t be defined. So, the maximum that <em>x </em>can be is 0, and 
. So, 0+2=2, and <em>y </em>is greater than or equal to 2.
Domain is x is greater than or equal to 0 because you cannot square a negative. So, it must not be less than 0. It could be 0 because square root of 0 is just 0.
