Answer:
9.38
Step-by-step explanation:
First let's start with what we know, we know the circumference and formula to get a circumference. (Formula: C= 2 π r) We also know how to find the circumference if we have the diameter. So what if we did it backwards? What if we divided? Let's try that, 29.48 ÷ π. Notice we don't put the radius because we don't know it yet. So when we do that on a calculator, we get 9.3885350 etc. Now we need to dived That by 2. That gives us 4.694267515 etc, but we can shorten that to 4.68. We're almost there! 4.68 is the RADIUS, not the diameter. so if you have the radius, you can easily get the diameter by mulitpling by 2. 4.68 x 2, is 9.38.

Answer:
D (compute the mean)
Step-by-step explanation:
A box plot is a visual representation of the 5-number summary of a set of data. It is plotted against a number line.
The 5-number summary of the data set is most easily determined from an ordered set of the data, so ordering the data is usually the first step. Since the 5-number summary is plotted against a number line, the next steps are finding the 5-number summary, and creating a suitable number line.
__
The business of adding the data and dividing by the number of data items is a description of computing the mean of the data. That value is not part of the 5-number summary, and is not needed in the creation of the box plot.
