Answer:
The radius is 4 feet
Step-by-step explanation:
<u>Area of a circle: A = π * r^2</u>
<u />
<u>Step 1: Solve for r</u>
16π / π = π * r^2 / π
sqrt(16) = sqrt(r^2)
<em>4 = r</em>

Answer:
128/15 or 8.53
Step-by-step explanation:
The minimum sample size required to estimate the mean usage of water = 2225.07
What is Standard deviation?
In statistics, the standard deviation (SD, also represented by the Greek letter sigma σ or the Latin letter s) is a measure that is used to quantify the amount of variation or dispersion of a set of data values.
We can find the minimum sample size required to estimate the mean usage of water as shown below:
Standard deviation 
Margin of error E=0.15
Critical value for 95% confidence interval = 1.96
Required minimum sample size: 

=2225.07
Hence, the minimum sample size required to estimate the mean usage of water = 2225.07
