If you have only been sleeping on your side, the technician may come into the room at some point and ask you to try to sleep on your back. If you never sleep on your back or cannot sleep on your back you do not need to do this in the study. Should I drink alcohol on the night of the sleep study?
To calculate the cross sectional area (CSA) of a cable, you have to use a micrometer to verify its diameter, then divide the diameter by two to get the radius (r).With the ra â¦ dius we can calculate the CSA of the cable.    CSA = pi x r2 (Applicable to solid wires only).se the formula pi x r2 (3.14 x radius x radius) to get the cross sectional area. The formula works for all measurement units whether they are inches, millimeters, centimeters or others. An alternative is to use (pi x d^2)/4. (3.14x diameter x diameter divided by 4) You do not then need to divide the original diameter.
There are other formulas for finding the area of a triangle depending on whether you know the length of the three sides, the length of one side of an equilateral triangle, or the length of two sides and their included angle.. Write down the formula for finding the area of the triangle. The formula for finding the area of a triangle with two known sides and a known included angle is the following: Area = 1/2(b)(c) x sinA. In this equation, b and c represent the lengths of the sides and A represents the angle.
