How do you get a circumference?
Using a compass and the circumference is measured by 2 times pi times radius or diameter times pi.
Why do we measure circumference?
The circumference is the distance around a circle and it is measured by:- Circumference of a circle = 2*pi*radius or pi*diameter
Formula for total area of a cylinder?
Total area measured in square units = (2*pi*radius2)+(pi*diameter*height)
Which is the formula for the surface area of a sphere with diameter d?
First divide the diameter by 2 to give the radius and use the formula:- Surface area of a sphere = 4*pi*radius2 measured in square units
When a pipe has an outside of diameter 42mm and a bore of 26mm find its cross-sectional area?
The cross-sectional area of a tube is equal to the area of the outer circle minus the area of the bore, so using the formula for area of a circle, we can do the following. A = pi*(42/2)2-pi*(26/2)2 = 272 pi, A = 854.513 mm2
Have 2 bore double rifles ever been produced and if so how much do they weigh in pounds?
Have never seen a double 2 bore. The single 2 bore weighs about 26 pounds.
What is 50NB pipe?
NB = Nominal Bore. Bore is the internal diameter of the pipe. The 50 is referring to 50mm (5cm). So it boils down to a pipe with an internal diameter of 50mm.
What is the effect of changing the engine cylinder bore diameter?
Enlarging the cylinder bore will increase cc's in a 2 stroke and ci's ina 4 stroke.....
What is the total surface area of a cylinder?
(2*pi*radius2) + (diameter*pi*height) measured in square units

What is the formula to find the surface area of short cylinder?
(2*pi*radius2) + (diameter*pi*height) measured in square units and including the two 'ends' of the cylinder
What is the formula for the force of a hydraulic cylinder?
Force=Area*PSI Area=Pi*R^2 Hope this helps For a double-acting cylinder: pi/4(d1^2-d2^2)y where: d1 = diameter of bore d2 = diameter of rod y = psi of system
Why do we measure circumference?

Total area of cylinder?
Total area = (2*pi*radius2) + (pi*diameter*height) measured in square units
Formula for total area of a cylinder?
Total area measured in square units = (2*pi*radius2)+(pi*diameter*height)
What size of packing should be used to repack a pump gland having 8.6cm stuffing box bore and 6.7cm pump shaft diameter?
The answer is 0.95 and how you figure it out is you take the stuffing box bore (8.6) minus the pump shaft diameter (6.7) which equals 1.9. you than divide that number by 2 which equals 0.95 so 0.95 is the size of your packing!
Which is the formula for the surface area of a sphere with diameter d?
First divide the diameter by 2 to give the radius and use the formula:- Surface area of a sphere = 4*pi*radius2 measured in square units
