The length of the band in terms of π is given by the expression:
L = 40mm + π*10mm
<h3>
How to get the length of the band?</h3>
Remember that for a circle of diameter D, the circumference is:
C = π*D.
Now, if you look at the image, you can see that the length of the band will be equal to 4 times the diameter of the pencils (one time for each side). Plus 4 times one-fourth of the circumference of each pencil (for the four corners).
because the diameter is 10mm, the length of the band will be:
L = 4*10mm + 4*(π*10mm/4)
L = 40mm + π*10mm
This is the length of the band in terms of π.

Answer: The answer is option D. <em>Delphi Method Linear regression</em>
Step-by-step explanation: The <em>Delphi method </em>is a forecasting process framework used to estimate the likelihood and outcome of future events by group of <em>expert </em>with <em>relevant Knowledge</em>. The group of experts exchange views, and each independently gives estimates and assumptions to a facilitator who reviews the data and issues a summary report.
The steps involved in delphi method are;
- Choose facilitator
- Identifying experts
- Problem definition
- Round one questions
- Round two questions
- Round three questions
- Findings and conclusion
Note:
- You may choose tom have more than three rounds of questions to reach a more accurate consensus
- This technique is an iterative process, which tends to get broad range of opinions from the group of experts who will aid generation of forecast
