When in MathIO the calculator displays pi symbolically. If you want the numerical value of an expression, press [SHIFT][=], not just [=]. You can try pressing the [SD] key to toggle between fraction`/radical to decimal. You can also configure the calculator to use LineIO by default.

What formula do you use to calculate cylinder volumes

Volumes are any three dimensional measurement...

I Seriously doubt that I could get Pi ("pie") to print...
But I'll just GIVE YOU the number (much simpler)
Pi = 3.14159

Inches, feet, yards or meters.. all the dimensions need to be in the same values... So if you have an inch "ruler"...
That is just fine...!!

Your first step would be to determine the diameter of the inside of your cylinder in inches...
CONVERT that to the RADIUS by DIVIDING by 2...
Multiply that RADIUS by itself and then by 3.1416 = area of circle in INCHES... (radius "squared" x Pi = (square inched)

Then MULTIPLY the height (in inched) by the AREA...

But I'll just GIVE YOU a REFERENCE (much simpler)
mathematical constant ?
Area of circle

Area of circle

(pi)R squared (Fixya won't let me use the sign for Pi)

Area of a circle=pi*radius^2 or pi times radius times radius

example: suppose the radius of a circle is 10 inches, then the Area of the circle would be pi times 10 times 10 or 100*pi

pi represents the circumference (distance around) of a circle / diameter and for any circle is constantly the same number which is approximately 3.14

so in my example 100*pi=100*3.14 or 314 square inches

Multiplying mixed fractions

Convert each mixed number (what you call mixed fraction) to an improper fraction, then multiply the two numerators and multiply the two denominators. Reduce the resulting fraction to its simplest form

(2 1/3)*(1 5/7)=?
Convert 2 1/3 to an improper fraction 2 1/3=2+ 1/3 = 6/3+1/3=7/3
Convert 1 5/7 to an improper fraction 1 5/7=1+ 5/7 =7/7 +5/7=12/7
(2 1/3)*(1 5/7)= (7/3)*(12/7)= (7*12)/(3*7)
The 7's in the numerator and denominator cancel one another leaving
(2 1/3)*(1 5/7)=4
Not all products of mixed numbers will give a simple result as this one. More likely they will not.

It wont give me the value when i multiply like 6 x pi

Your calculator may be able to use the symbol Pi. If it gives you a result with Pi, you should convert it to a decimal approximation. There must be a key to convert.

When i try to use the pi key with another operation it does not compute. For example if I am trying to multiply 10 times pi, the calculator reads 10pi

Press the FD (fraction to decimal) button after you calculate 10 times pi, This will give you the
calculation in decimal form.

How do I generate a random number that is greater than 1 on a casio fx-300MS

The random number function always generates a number between zero and one. You can convert this to a random number in any range by a suitable combination of multiplications and additions. For example, if you want a random number between zero and ten, multiply the generated random number by 10. If you want a random number between one and ten, multiply the generated random number by 9 and then add 1.

If you want to simulate the roll of a six-sided die, multiply the generated random number by 6, add 1, and ignore the fractional portion. This will give you a 1, 2, 3, 4, 5, or 6 with more-or-less equal probability.

Need tub capacity

Things You'll Need:

* Measuring tape


Measure the depth from inside the washer with a measuring tape. Start from the back of the inside of the washer towards you to the front of the washer. Measure the depth from a top loading washer from the bottom of the inside of the washer to the top. For example, a washing machine may have a depth of two feet.

Measure the height inside the washer unit. The height inside the washer is from the bottom of the inside of the washer to the top of the inside of the washer for a front loading washing. The height is from one side of the inside of the washer to the other side in a top loading washer. For example, the inside of a washer may be one and a half feet, or 1.5 feet.

Divide the height calculated in step 2 by two, and square it. In the example, 1.5 divided by two equals 0.75, and 0.75 to the power of 2 equals 0.5625.

Multiply the number calculated in step 3 by the depth of the washing machine. In the example, 0.5625 times two equals 1.125.

Multiply the number calculated in step 4 by Pi to determine the capacity. Pi is generally estimated as 3.14. In the example, 1.125 times 3.14 equals a washer capacity of 3.5325 cubic feet

How do you use the pi button? I want to multiply 42 by pi and it gives me the answer of 42pi.

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.
