Do you multiply when you find the diameter?
I assume you want the formula for finding the circumference of a circle with a known diameter?The formula is C = pxdC = Circumferencep = Pi (3.14)d = DiameterFor example: with a diameter of 6 : 3.14 x 6 = 18.84
What is the perimeter of Mars?
I suggest you assume it is a sphere, look up its diameter, and multiply that by pi. That should be close enough.
If a watch is 44 diameters how many inches is that?
I assume you mean 44mm diameter. 1 inch = 25.4mm 44mm = 1.73 inches
What does the surface area of an object have to do with the amount of pressure it can exert?
It only has to do with the surface area in contact with the support force (the side or surface that is in contact with the ground, table, etc.). If you have two cans, each with 3 solid bricks on top of them. One can has a diameter of 3 cm, while the other has a diameter of 5 cm. Which one has greater pressure? The can with a diameter of 3 cm. This is because there is less surface area in contact with the support force, so there is less area to distribute the force. Pressure is inversely related to area. Remember that pressure is measured in Pascals. Pressure is equal to Force over Area or p=F/A. Assuming that both cans have the same weight with the bricks on top. Lets assume each weighs 5 kilograms. So the pressure for the 5 cm can would be 5 kg (weight) * 9.8 (Gravity force) / 5 cm * pi (Area) or about 3.12 Pascals. Our 3 cm can would be 5 kg * 9.8 / 3 cm * pi or about 5.20 Pascals.
What would the area and perimeter be if the diameter is 6cm?
You said "diameter", so we'll assume that you're talking about a circle.Circumference of a circle (distance around, 'perimeter') = (pi) x diameter = 6 pi = 18.85 cm (rounded)Area of a circle = (pi) R2 = (pi) x (1/2 of the diameter)2 = 9 pi = 28.27 cm2 (rounded)
How do you find the area using the diameter?
I assume that you are referring to the area of a circle. You divide the diameter in half to find the radius and then you put it into the formula.
What star is only about 20 km?
Diameter, I assume. That would be a neutron star.
How many linear INCHES in a 37 inch diameter circle?
I assume you want the circumference which is pi times the diameter, so for 37 inch diameter the circumference would be about 116.24 inches.
What is the partial pressure of nitrogen in air at 1 atmosphere pressure Assume ideal behavior.?
.78
As pressure increase what does volume do?
since PV=nRT and we assume that the number of moles and temperature remains constant, we can assume that PV=R as R the gas constant will not change, if pressure is increased, then volume must decrease to counteract the change in pressure
Why does the vapour pressure of water contribute to the total pressure in the bottle?
by equalizing water levels you can assume that the gas you isolated in the chamber is at atmospheric pressure

If a circle has a circumference of 100 feet what is the width?
With "width", I assume you mean what is commonly called the diameter - the distance through the center. The circumference is diamter x pi, therefore, the diameter is the circumference divided by pi. In other words, just divide the circumference by 3.14, approximately.With "width", I assume you mean what is commonly called the diameter - the distance through the center.

What is the symbol for pressure when measured in pascals?
Pressure is always to my knowledge a P. I assume you mean the symbol for pascal though. This is Pa
What is the deffinition of pi?
I assume that you mean "the 'definition' of pi", which is the circumference of a circle divided by it's diameter (c/d).

How do you convert a differential pressure of 43 psi to absolute units?
Let's assume one of the inlet ports is at atmospheric pressure, Absolute pressure = atmospheric pressure + differential pressure = 14.7psi + 43psi = 57.7 psi
