Answer:

Step-by-step explanation:
From the question we are told that:
Diameter 
Radius
Generally the equation for Circumference of a circle is mathematically given by


Answer:
gm =14sqrt(2)
or approximately 19.8
Step-by-step explanation:
to find the geometric mean, multiply the numbers together and then take the square root
gm = sqrt(28*14)
gm = sqrt(392)
gm = sqrt(196*2)
gm =14sqrt(2)
gm = 19.799
Answer:
The correct options are 2 and 4.
Step-by-step explanation:
From the given box plot it is clear that





We know that these number divides the data in four equal parts.



25% of the data values lies between 50 and 110. Therefore option 1 is incorrect.
Seventy-five percent of the data values lies between 20 and 50. Therefore option 2 is correct.
It is unlikely that there are any outliers. This statement is not true because the is a huge difference between third quartile and maximum value.
Therefore option 3 is incorrect.
The interquartile range is

Therefore option 4 is correct.
The range is
Range = Maximum-Minimum

Therefore option 5 is incorrect.
