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".

How do you use pi to determine circumference?

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


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.


Is circumference radius times pi?

NO!!!! C = 2 pi r C = pi d In words ; Circumference equals two times 'pi' times radius or , circumference equals 'pi' times diameter. NB The diameter is twice the radius. Also A = pi r^(2) In words, Area equals 'pi' times the radius squared. Read learn and comit to memory these two circle equations.
