    • circumference - its basically the outline / perimeter
    • sector - a portion of the circle that has been formed from the centre
    • chord - a line from any position of the circumference to another point (creating a segment) that is straight and doesn't go through the centre
    • diameter - a straight line exactly through the middle of the circle
    • radius - a straight line from the centre of the circle to any other point on the circumference
    • tangent - a line that just touches the edge of the circle
    • segment - a fraction / portion of the circle that is outlined by the circumference and chord
    • arc - portion of the circumference
    • pi - 3.141592653589793238462643383279502884197169399375105820974944592307816406286208998628034825342117067
    • to work out circumference - 2 X pi X radius
    • to work out area - pi X radius X radius
