Extra Information

A sector of a circle) is made by drawing two lines from the centre of the circle to the circumference. Do NOT confuse a 'sector' with a 'segment'. A segment is the shape formed between the chord and the arc. If the angle is 180 degrees then the sector is a semi-circle. If the perimeter is needed, add together the lengths of: radius + radius + arc
