Covers the material on the Edexcel Maths specifications - linear and modular on which students sitting the foundation tier exam paper may be tested.The diameter is the distance from one side of the circle through the centre, ac, to the other side of the circle, which therefore means that. ... Calculate its circumference using n Al 3.14 We use this formula since we are given the RADIUS Using our formula: C = 27tr C = 2 x 7i x 2cm C = 2 x 3.14 x 2cm C ... The length of an arc is given by: Length of Arc = rjjjs x 27tr Where 6 is the angle at the centre of the circle.
