Answer:
4in = r
Step-by-step explanation:
Different problem if the x was a variable in the question
formula for area of circle = pi x r^2.
So if the area of a circle is 16 pi in^2, it would be an obvious estimate that the radius is the square root of 16 which is 4 inches.
If the x was a variable, you would find the square root of 16x which is 
which would make it 4
as the radius.
<u>Coverage Error</u> results from the exclusion of certain groups of subjects from a population frame. The answer for the given statement is Coverage Error.
<h3>What is Coverage Error?</h3>
Coverage errors come from failure to cover sufficiently all components of the population being studied. Incomplete sampling frames usually result in coverage errors. Coverage errors happen because of the divergences between the target population and the frame.
Coverage error also may happen when not all members of the population of interest have an equal chance of being selected for the survey. For example, if we use e-mail lists or phone lists to build the sample and not all potential respondents are on those e-mail or phone lists.

Answer:
length of the side of the square = 4
Step-by-step explanation:
All the sides of a square are equal in length.
So, let's get the unknown side be x.
Area = length × width
16 = x × x
16 = x²
√16 = x
4 = x
Length of the side of the square = 4
