How does circumference relate to area
WebCircles are not all congruent, because they can have different radius lengths. A sector is the portion of the interior of a circle between two radii. Two sectors must have congruent central angles to be similar. An arc is the portion of the circumference of a circle between two radii. WebCircumference = 2 pi sinh r Area = 4 pi sinh 2 ( r /2) where r is the radius of the circle.
