If the point of the central angle of an arc is also the midpoint of a circle (that contains your arc) then the arc is is equal to your central angle.
The arc length is just a fraction of your circle's circumference.
The area of a sector of a circle is just a fraction of the area of your circle.
The formula for arc length is (Pi*R*2)*A/360, where R is radius, and A is angle measure.
The formula for sector area is (Pi*R^2)*A/360, where R is radius, and A is angle measure.
