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.

What is the Formula for calculating volume of a cylinder


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 )

A train leaves Middelburg at 09:00 and arrives in Johannesburg at 11:00 having traveled a distance of 180 km. Find the average speed of the train in m/s.


Journey time 2hrs = 2 x 60 mins = 2 x 60 x 60 seconds
Distance 180 km = 180,000 m
Average speed = 3 x 6 x 10000 / 2 x 6 x 6 x 100 m/s
= 6 x 6 x 100 x 100 / [2 x (2 x 6 x6 x100)] m/s
= 100 / 4 m/s
= 25 m/s

I am horrible at maths need help asap


With algebra you are learning problem solving-that is the process of problem solving using rules and equations. The best way to learn it is to shut out all distraction and work at it. If there is something you don't understand you may have to go back to the beginning and learn all the principals and rules that you don't understand- Algebra can be a very hard subject but it can be concord with persistence.

Mdas problem solving


if you mean {7(2)2+[(3-2)-4x(3)]2} or 7(2)2+[(3-2)-4x(3)]2
{28+[(1)-12]2}
{28+[-12]2}
{28+-24}
=4
or if it was 4x not 4 times
{7(2)2+[(3-2)-4x(3)]2}
28+[(1)-12x]2
28+-24x
=-28x+28

The circumference of a circle is 47.1 feet. What is the diameter of the circle?


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
