A radius is a chord of a circle?
No. A chord is a straight line within a circle that meets the circumference at two points and divides the circle into two arcs. A radius is a straight line from the centre of the circle to the circumference and is therefore not a chord. However, a diameter is a chord passing through the centre of the circle.
If you calculated the circumference of a circle the size of the known universe requiring that the answer be accurate to within the radius of one proton how many decimal places of pi would you need t?
That's a fascinating question. I have an answer, but it's one that I'm not100% sure of in my own mind, so I'm going to call itAnswer #1:I think the accuracy of the value you calculate doesn't depend so much on theconversion factor you use, but more on the accuracy of the data you start with.So it makes no difference what value you use for PI, unless you start out with anumber for the radius of the observable universe that you know to be accurateto within the proton radius. If your radius isn't that accurate, then there's nothingyour proportionality factor can do to it to fix the answer. Whatever radius you startwith, if you use one more significant figure of PI than the significant figures youhave in the radius, the accuracy of the radius is preserved in the circumferenceyou calculate.That's my suspicion.
What's the formula for circumference of a circle?
Circumference of a circle is denoted as C in geometry. The formula to calculate circumference is: C=2πr where: π = 22/7 r = radius Note, radius is half of diameter (the line that touches two sides within circle and passes through the center of the circle)
Is pi a variable?
No. It is a constant. The Greek letter pi is used to denote the following: A fundamental mathematical constant defined as the ratio of the circumference of a circle to its diameter. It is a transcendental number with the decimal expansion 3.141 592 653 589 79...More than a trillion decimal places have now been calculated; just 39 places are sufficient to compute the circumference of the observable Universe accurate to within the radius of a hydrogen atom.(According to the Penguin Dictionary of Science)
What would be the radius of the circle which rolls on the circumference of the pitch circle while generating cycloidal gear teeth profile?
This is a trick question. Is the cycloid axis on the inner or outer circumference? Let us take a mid-line. When generating a profiles like teeth or anything else the shape is not a perfect circle. One must then take the innermost and outermost radii and calculate an average. For cycloidal profiles the radius of the circumference ids simple based on the pitch height. The value becomes much more accurate if one uses Gauss's formula. Anyway, the value should be within about 5% of the value of that radius of the pitch circle if the profile relates to human teeth or even double for a pure carnivore.

When will a black hole hit your universe?
There are already black holes within the universe
What is the time-line of the discovery of the universe?
The universe is older than mankind and mankind evolved within the universe. So the universe could not be discovered.
Define an local business?
A local business is a business located within a close geographical radius. Lets say a local party store is probably within a 5 mile radius of your house. Depending on the type of business, will determine the radius.
What it will be the result of reversing the spin of the universe?
Matter within the universe has the property of angular momentum, but the universe itself does not appear to spin.
