If theta is the angle from the center of the circle to the edges of the chord, then
chord length = 2Rsin (theta/2)

There is no direct relation between the area of a sector and the length of an arc. You must know the radius (or diameter) or the angle of the sector at the centre.
The diameter of a circle if twice the length of the radius.
The relationship between the chord and the radius of the circle is Length of the chord = 2r sin(c/2) where r = radius of the circle and c = angle subtended at the center by the chord
Length of a radius is always half the diameter of a circle. This means that the circle has a radius of 2cm.
The length of the space between two sides of a circle passing through the radius, Alternatively it is twice the length of the radius. This is the distance from the centre of the circle to any point on the circumference.
