An introduction of pi?
Pi is the ratio of the circumference of a circle to its diameter; it can be calculated as circumference divided by diameter, or circumference/diameter. It is an irrational number which starts 3.14159265358979323846264338327050..., but it is usually approximated to 3.14 or 22/7, though using the [π] button on a calculator makes it easier to enter a fairly accurate value.
What unit of measure is a diameter?
A diameter is a line and can be measured in any units of length although some may be more useful units than others. The diameter of a galaxy may be measured in light years, that of a ferris wheel in metres, a car tyre in centimetres, etc. The diameter of a galaxy may be measured in centimetres but you'll simply end up with a very large number.
What is the formula for circumference of a circl?
The circumference of a circle is the length around it. The circumference of a circle can be calculated from its diameter using the formula: Circumference of a circle = 2*pi*radius orCircumference of a circle = pi*diameterwhere r is the radius and d is the diameter of the circle, and � (the Greek letter pi) is defined as the ratio of the circumference of the circle to its diameter.(the numerical value of pi is 3.141 592 654 589 793...).d * pior 2 * r * piWhere d is diameter and r is radius and pi = 3.14159
What is the circumference of a 4 foot circle?
The circumference of a 4 foot diameter circle may be obtained by multiplying the diameter by pi, which is 3.1416 4 X 3.1416 = 13 (rounded to the nearest whole number)
If the circumference of a circle is 16 feet what is the diameter?
Diameter = Circumference / Pi Diameter = 16 / 3.14 Diameter = 5.095
How do you choose bevel gear diameter?
the inner diameter is the shaft diameter the out diameter you have to calculated
How is the diameter calculated when the circumference is known?
The diameter is the circumference divided by pi. (3.14159...)
How is the medullary index of hair calculated?
The medullary index measures the diameter of the medulla relative to the diameter of the hair shaft. MI= Medulla Diameter -------------------------- x 100 Hair Diameter
A circle has a diameter of 16 and the area of 64 Pi find the radius?
In this case, the radius is easiest calculated from the diameter. The radius is simply half the diameter.
What is the circumference of a circle that has a diameter of 8 m?
25.1327m. It is calculated by mutiplying the diameter by pi, which is a constant equal to 3.14159265....
How do you calculated throat diameter for venturi tube?
Using Bernouli's Equation.
How can the circumference of a circle be calculated?
The circumference of a circle can be calculated by multiplying pi by the diameter of the circle. For example if the diameter is 10 then the calculation will be pi x 10 = answer. The most commonly used value for pi is 3.14
How is pi related to the circumference area of a circle?
Pi (approximately 3.14) is the ratio of the circumference of a circle to its diameter. It is calculated by circumference divided by diameter.
What is the diameter of a meteorite?
The diameter of a meteorite may vary greatly.
Formula module in helical gear?
the module of a helical gear is calculated in the same way of that of a spur gear: module=pitch diameter / no of teeth the module of a helical gear is calculated in the same way of that of a spur gear: module=pitch diameter / no of teeth
What is the formula for the circumfriss of a circle?
It is called circumference. This is usually calculated from the diameter (circumference = pi x diameter), or from the radius (circumference = 2 x pi x radius).
What is the area of a circle that has a cm diameter?
The area of a circle is calculated from the formula Pi x r2 . A 1cm diameter circle has a radius of 0.5cm, thus it has an area of 0.785cm2
