Answer:
<em>38 inches</em>
Step-by-step explanation:
The cookies is in the shape of a circle. The formula for the area of a circle is:

Where r is the radius
The area is given as 113, so we can find the radius:

We need to find the circumference, which has the formula:

Where r is the radius (We got r = 5.997)
We substitute and find:

So, the circumference is 37.68 inches.
<em>Rounded to nearest inch, that would be:</em>
<em>38 inches</em>
Answer:
V = 1316.4 m^3
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
V = 4/3 (3.14 ) ( 6.8) ^3
= 1316.421973 m^3
Round to the nearest tenth
V = 1316.4 m^3
Using the z-distribution, as we have the standard deviation for the population, it is found that the smallest sample size required to obtain the desired margin of error is of 77.
<h3>What is a z-distribution confidence interval?</h3>
The confidence interval is:

In which:
is the sample mean.
is the standard deviation for the population.
The margin of error is given by:

In this problem, we have that the parameters are given as follows:
.
Hence, solving for n, we find the sample size.






Rounding up, the smallest sample size required to obtain the desired margin of error is of 77.
