Do you want combinations or permutations? They're different things. A combination of n items taken m at a time, sometimes written "nCm", selects m items from a group of n without regard to order. A permutation of n items taken m at a time, sometimes written "nPm", selects m items from a group of m with regard to order.

Given six numbers, there are six combinations of one number, 15 combinations of two numbers, 20 combinations of three numbers, 15 combinations of four numbers, six combinations of five numbers, and one combination of six numbers.

Given six numbers, there are six permutations of one number, 30 permutations of two numbers, 120 permutations of three numbers, 360 permutations of four numbers, 720 permutations of five numbers, and 720 permutations of six numbers.

1and 5/7 ==1.7142 (5/7 to get decimal point=.7142)

+ 9 divided by minus 1.7142= minus 5.1688

using the maths laws of multiplication and division of numbers where + and - indicies are used +X+ =+ and + X - = - and - X- = +

you will find answers on the web maths pages

volume is calculated by finding the area multiplied by the length or height . That is Pi X radius squared X length

example --tube 6"dia 12"long what is the volume?

Example 3.1417 X radius 3" Squared =3.1417X9sq " = 28.2740sq" X length 12" =338.688 cubic"

If you want the volume of an engine cylinder , it is the same formula and the length is the stroke of the piston ( distance from TDC to BDC )

Circumference of a Circle: 2 x pi x radius - OR - pi x diameter,

or if you need some sphere calculations?

Sphere Surface Area: 4 X pi X radius squared OR

pi X diameter squared Sphere Volume: 4/3 X pi X radius cubed OR

( pi X diameter cubed ) / 6

By the way.......... "pi" = 3.1415926536

Use the words: decimal part, not decimal fractin

**Any number whose decimal part is periodic (has a recurring pattern that repeats indefinitely) is equivalent to a rational number, IS a rational number**

0.345 345 345 ... =345/999=115/333

In the following screen captures, discard the last digit if it does not belong to a period. It is the effect of rounding up of the calculator

**Period is 345**

**Period is 1**

Period is**09**

Period is** 79**

In general, if you have a decimal part of the form 0.d_1 d_2 d_3....d_n d_1 d_2 d_3 ...d_n ... where d_1 is the first digit of the period, d_2 is the 2nd digit of the period, ..., d_n is the n-th digit (and the last one) of the period, then the fraction representation of

0.**d_1d_2...d_n** d_1d_2... d_n ...=(**d_1d_2...d_n**)/(99...9) where the number of 9's in the denominator is equal to the number of digits in the period.

Once the fraction is found, one should reduce it to its simplest form.

0.345 345 345 ... =345/999=115/333

The circumference of a circle is C=2 * pi * r or C= pi * d.

What do we know? C=47.1 and pi.

What are we trying to calculate? d

Put what we know in the equation and solve for d.

47.1 = pi * d

To isolate d, we have to divide both sides by pi.

47.1

------ = d

pi

I get 14.99' or approximately 15' as the diameter.

Good luck,

Paul
