Circumference: C = 2πr or πd, where r is the radius of the circle and d is its diameter. Area: Area Circle = πr 2 . Arc length: The length of an arc (part of the circumference) is equal to the circumference of the circle (2πr) times the fraction of the circle represented by the arc. The perimeter of a polygon is equal to the sum of the length of its sides. P(A or B) = P(A) + P(B) – P(A and B) Below are the formulas you may find useful as you take the test.
