I don't think you can change the pi value on your calculator. However, what you can do is store 3.14 in the memory and instead of using the pi key, recall the number from the memory key.

How to use the various memory keys is outlined in the manual.

Good luck,

Paul

Th formula is PI *dia.

Pi is available on this model using Shift key + X10 key at middle bottom.

So enter Pi then key x (multiply) then enter diameter then = key.

The calculator has two Input/Output Modes: The MathIO and LineIO modes. Line IO is the old input mode where all symbols are written on a single line. MathIO permits fractions to show as they would in a textbook (a horizontal fraction bar and two squares, one on top and the other at the bottom. Pi can be used as Pi and irrational square roots are displayed with the root symbol. etc,,

If you are in MarhIO and you get a result with fractions, radicals, or pi. you can readily convert it to its decimal approximation by pressim the SD key. If you enter some expression with fractions and radicals and you do not want the result displayed with fractions or radicals you press SHIFT = instead of =,

Now if you do not care to have ANYTHING displayed as a fraction, radical or with PI, just set the IO mode to the old LineIO.

To effect that, press SHIFT MODE to enter the SETUP. Select 2:LineIO. From that moment on you will no longer see a fraction, nor a radical nor PI, e,

If you ever reset the calculator, the MathIO mode will be restored as default IO mode.

The "problem" is not how to calculate with numbers expressed in Scientific Notation but how to enter a number given to you in scientific notation. Once the number is entered you do not have to do anything special. If you have to multiply it use the (x) button. to add it use the + button, etc.

How to enter a number in scientific notation.

Type in the mantissa (example 6.022)

Press the [X10^x] at the bottom of keypad.

Enter the exponent (example 23)

with this example you will have entered Avogadro's number 6.022x10^23

Other example

1.6 [X10^x] (-) 19 enters the electron charge in Coulombs. The exponent is negative that is why you press the change sign key (-).

Almost exactly the way it's written in the book.

In the LineIO mode press

3 SHIFT [xth-root] 5 0 0 0 * 3 / ( 4 * SHIFT [pi] ) ) =

In the MathIO mode press

SHIFT [xth-root] 3 right-arrow 5 0 0 0 * 3 / ( 4 * SHIFT [pi]) =

xth-root is the shifted function of the key just below and right of the big round cursor pad.

* is the multiply key

/ is the divide key

pi is the shifted function of the x10^x key in the middle of the bottom row

BTW there's no "square root" in this problem. There's a "cube root" or "third root". Square root is the second root.

try 4 x 3.14 (PI=3.14)

There is no built-in conversion for this. The simplest way to do this is to multiply by pi and divide by 180 (or divide by 180 and multiply by pi). If you have to do this often, you can store the constant pi/180 (or 180/pi) in memory and use that instead of doing the calculation again and again.

Well, 42pi is the result of multiplying 42 by pi, isn't it? In the default MthIO mode the calculator strives to display as many results symbolically as possible.

To convert a single result to decimal, press SD. To have all results come out in decimal, press SHIFT MODE 2 to select the LineIO mode.

Multiply it by 180 and then divide by PI.
