The area sector of a circle needs pi to work it out.
Twice the radius times pi or the diameter times pi
Yes
The circumference of a circle is (pi) x (diameter), or (2 pi) x (radius).
pi times the radius squared or pi (approx 3.14) times the diameter
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
