Other qustion 1.5 spilt lg ac not getting cool i called ac technician he told gas not there he filled the gas it was working 3 days he told to convert the alluminiam to copper is it correct

aluminium works more efficiently than copper in transferring heat and aluminium units last up to 20 years or 15 years in coastal regions
if there is a gas leak due to corrosion of the aluminium he may have a point , but one has to question the cleanliness of the system internally as if it has not been vacuumed out properly before adding gas , the moisture that remains in the pipes will react with the gas and oil and will corrode the tubes internally
best to get a second opinion before committing to expensive replacements

What is the area of a circle if the circumference is 2 pi inches

area formula is PI x r squared
that is 3.1417 times the radius of the circle squared
example is:- 3.1417 times 3 inches squared =3.1417 times 3x3=3.1417x9=28.279 square inches if you want to work back from a circumference measurement, the formula for circumference is 2 x PI x radius or PI x diameter
if you have a circumference of 12 inches then the dia is calculated 12 inches = dia x PI to get the diameter , divide the 12 inches by PI and that will be the diameter so that is 12 divided by 3.1417 =3.819 inches
now you can go from the first formula the radius is the diameter divided by 2 so the radius will be 3.819 divided by 2 = 1.909 inches
so applying the area formula it becomes 3.1417 times 1.909 times 1.909 =11.458 square inches
to find your answer simply substitute the dimensions in place of the example the relevant formula.

What size are the starter bolts on a 2002 dodge stratus. i broke one and it seems longer than the other

You mean metric diameter & thread pitch?

You will have to mic the diameter & convert
to metric or just match up at a store

As a guess only--dia may be 1/2 "or 12mm & length say
2" or 50mm

.0395 is (1) mm

Whatever you measure dia or length wise, you
divide by .0395 to go to metric

They heat treated bolts,not a Home Depot
chinese item

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 )

The seat is held down by pillar bolts through the pan and plastic wing nuts which are too tight to remove by my fingers. they are accessible only via a hole (120mm dia or so) in the back of the pan. I...

You can get special plastic sockets to fit the wing nuts from most good DIY stores - they are a standard size. The bolts may be a bit corroded up inside the nuts so give a quick squirt with WD40 or other silicine based lubricant / dismantling spray.
If you can't get the special tool find a piece of rigid plastic pipe about 6-8 inches (150-200mm) long and about 3/4"-1: (20-25mm) in diameter - should be able to buy a length of it in plumbing department of store. With a hacksaw make two cuts vertically down about 25mm (1 inch) on the end of the pipe - about 5 or 6 mm 1/4 inch a part. You should be able to push this over the lugs of the wing nuts. The length of the pipe should give you enough grip to be able to turn the wing nuts. If you need more leverage drill a 6 -8 mm hole right through the plastic pipe at opposite end from the saw cuts and push a stout screwdriver through the hole to use as a tommy bar

My pipe trades pro when solving a rolling offset only gives me 0.0 degrees

Hi jlight49,

Your Pipe Trades Pro calculator from Calculated Industries comes with FREE technical support:

It is hard to tell from the description of your issue, but when working with a rolling offset, the [Angle] will show 0.00. All the rolling offset outputs are accessed through the second function of [Travel] which is labeled as [Roll].

The key sequence is:
-enter your rise into [Offset]
-enter your advance into [Run]
-enter your roll into [Roll] by pressing [Conv] [Travel]
-press [Travel] repeatedly to see the rolling offset outputs, starting with Length, followed by Fitting Degree, etc.

Contact technical support and they will help you out!

Baseboard such as Slant-fin is made with a bracket that will allow you to run a 3/4" dia copper pipe back over the top of the finned area as a return pipe giving you a supply and a return on the same side.

Calculation of cylinder capacity

volume of a cylinder = height time Pi r squared

dia = 43cm so radius = 21.5cm

so 109 x 3.14 x 21.5squared = 158209.69 cubic cm

1 cubic cm = 0.001 litre

so 158.20969 litres

with a more correct value for Pi is actually 158.28993 Litres
