The area of your circle is about 530.93 m
The diameter of your circle is 26 m, just multiply your radius by 2
The circumference of the circle is about 81.68
The equation to finding the area is
pi x r x 2
3.14 times 13 times 2
The equation to finding the diameter
r x 2
radius times 2
The equation for finding circumference
pi x d
3.14 times 26
Let me know if im wrong, otherwise I want brainliest, PLEASE!!

The correct answer for the question that is being presented above is this one: "b. $2.78." Andrew owns stock in Hyren Airlines and as a result gets paid dividends worth $539.70 every year. If Andrew owns 105 shares of Hyren Airlines, the dividend of each share yields <span>b. $2.78</span>
Answer:
A sample size of 35 is needed.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the width W as such
In which 
is the standard deviation of the population and n is the size of the sample.
How large must the sample size be if the width of the 95% interval for mu is to be 1.0:
We need to find n for which W = 1.
We have that 
, then 
. So
Rounding up
A sample size of 35 is needed.
