pi is just a number, it is not a machine. It is defined as the circumference/diameter of any circle, the result although defined by a ratio is an irrational number (can't be writt
en as a ratio of integers).
Pi is also, 3.14, as in the distance of a circle.
The value of pi = circumference/diameter
Circumference = pi*diameter or 2*pi*radius
The area sector of a circle needs pi to work it out.
Twice the radius times pi or the diameter times pi
Yes
The value of pi = circumference/diameter

The area sector of a circle needs pi to work it out.
Twice the radius times pi or the diameter times pi
Yes
pi times the radius squared or pi (approx 3.14) times the diameter
The circumference of a circle is (pi) x (diameter), or (2 pi) x (radius).
The question is in really bad english, but I'm guessing your meant: 'How do I work out the diameter using pi?' Diameter= Radius2 You don't need to use Pi to work out the diameter. Unless you have a question that doesn't show you the radius. Then you do Area divided by Pi which equals the Diameter.
It is pi r 2
