# Unit 2 Worksheet 2 Measuring Pressure

The second lesson is that you need to know how to measure the area of a disk from one point to another point. This is why you can’t just write a line in a column on a piece of paper and then read it off of the disk.

It doesn’t make any sense at all. I couldn’t even believe that this was taught in school, but it’s a real life issue in high school. So, we are going to teach you how to do this so that you can use it.

The first step to doing this is to click on the “Document” tab. At the top of the screen is the “Unit” tab. The first step is to turn this back on. So, go to Unit 2, and click the plus sign.

You are going to see the “Measure Units” option come up. This will give you all the features that you need to use this tab. Here, you are going to put the number of lines that you want to use to measure the area of the disk, and the number of points.

For our example, I’m going to use two lines. So, I’ll put that number on the “Display Number” box, and I’ll click the button with the “0” beside it. If you had used the two-point method, the units for this number would be “inches”.

Now, when you click the buttons to increase the numbers for the two lines, or to increase the number of points, they will change the output from “inches” to “centimeters”, or “centimeters” to “mm”. The only thing that you can’t change is the type of disk that you’re looking at.

So, now that you know how to do this, click the “Close” button and then write down the results. At the bottom of the worksheet, there is a column heading with a heading that says “Area”. Write down the results in that column.

So, the last lesson is to learn how to measure the area of a disk from one point to another point. We did it using two different methods. So, now that you know how to do it, you can do it without worry.
