How do you get a calculator to answer in terms of pi?
Just ignore pi and do “11/59 + 28/13” first and that will give you the fraction. Then include pi alongside it, job done. Also when doing something like inverse cosine of a number, you’re not always going to get a multiple of pi for your calculator to show, so don’t expect it every time.
How do you do pi?
The circumference of a circle is found with the formula C= π*d = 2*π*r. Thus, pi equals a circle’s circumference divided by its diameter. Plug your numbers into a calculator: the result should be roughly 3.14. Repeat this process with several different circles, and then average the results.
How do you turn your answer in terms of pi?
Give your answer in terms of pi? Answer: Square the radius and multiply by Pi.
How isoelectric point is calculated?
These amino acids are characterised by two pKas : pKa1 and pKa2 for the carboxylic acid and the amine respectively. The isoelectronic point will be halfway between, or the average of, these two pKas, i.e. pI = 1/2 (pKa1 + pKa2).
What is isoelectric point in chemistry?
The isoelectric point (pI) is the pH at which a particular molecule carries no net electrical charge. The net charge on the molecule is affected by the pH of its surrounding environment and can become more positive or negative due to the gain or loss of protons, respectively.

How do you calculate pie in math?
Calculate the surface area of a pie by multiplying Pi times the pie radius-squared, where Pi is 3.14 and the pie radius is a given number represented by “Pie-R”. In other words, Area = Pi * Pie-R-squared.
How do you calculate pi in finance?
The Profitability Index (PI) or profit investment ratio (PIR) is a widely used measure for evaluating viability and profitability of an investment project. It is calculated by dividing the present value of future cash flows by the initial amount invested.
