The number tau (τ) is a mathematical constant which is equal to 2 × π. It is not nearly as universally recognized as π and some call it "pi with three legs".

Why is circumference equal to 2 times Pi times r?
circumference=pi circumference=pi circumference=pi
Is circumfrience pi times radius to the 2?
circumfrience is pi times radius to the 2 i think
Why is the circumference of a circle diameter times pi or 2 radius times pi?
Because 2 times the radius is equal to the diameter of the circle
Is 2 pi a rational number?
No, since Pi is an irrational number, 2(pi) would still be irrational.
How do you calculate the circumference if you know the diameter?
Circumference is equal to 2 times pi (3.1416) times one half of the diameter (the radius). So, if the diameter is 2 cm, then the circumference would be the product of (2) times (3.1416) times (1), or 6.2832 cm. Circumference is equal to diameter times Pi. c = Pi * d diameter times pi
What are the two formulas for circumference?
C= 2 times pi and C= pi times diameter C= 2 times pi and C= pi times diameter
What is pi times pi equal?
pi^2
What is 4 times pi times pi times 4 divided by 2?
4 times pi times 4 divided by 2 is 78.9568352087
How do you multiply two times pi times two?
2 x pi x 2 = 4 x pi
Why is circumference equal to 2 times Pi times r?
circumference=pi circumference=pi circumference=pi
Is circumference radius times pi?
No it is 2*radius*pi or diameter*pi or 2(pi)r
How do you use pi to determine circumference?
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
Is circumfrience pi times radius to the 2?
circumfrience is pi times radius to the 2 i think
What is Pi 1 times 1 times 2 divided by 3?
It is 2*pi/3.
What does pi radius 2 mean?
That would depend if you mean 2 times the radius times pi (2*pi*r) or the more likely scenario pi times radius squared (pi*r2). 2*pi*r is the formula of the circumference of a 2d circle. Pi*r2 is the formula of the area of a 2d circle.
What is the formula for the area of acircumferenceof a circle is?
area: (pi) times radius2 circumference: (pi) times diameter OR 2 times (pi) times radius :)
What is the formula to find the cercumfrence?
2πr (2 times pi times the radius, or pi times the diameter)
