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".

circumfrience is pi times radius to the 2 i think

Because 2 times the radius is equal to the diameter of the circle

No, since Pi is an irrational number, 2(pi) would still be irrational.

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

No it is 2*radius*pi or diameter*pi or 2(pi)r

Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)

circumfrience is pi times radius to the 2 i think

It is 2*pi/3.

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.

area: (pi) times radius2 circumference: (pi) times diameter OR 2 times (pi) times radius :)

2πr (2 times pi times the radius, or pi times the diameter)
