Diameter: A diameter is a chord that runs through the centre point of the circle. It is the longest possible chord of any circle. The centre of a circle is the midpoint of its diameter. That is, it divides it into two equal parts, each of which is a radius of the circle.
Radius: From Latin: radius "staff, spoke of a wheel" 1. A line from the centre of a circle to a point on the circle. 2. The distance from the centre of a circle to a point on the circle.
Pi: Pi is a ratio of the circumference of a circle's to it’s diameter. In another word, pi equals the circumference divided by the diameter. Circumference is equal to pi times the diameter. No matter how large or small a circles is, pi will always work out to be the same number. Pi is an irrational number, which means that is a real number with nonrepeating decimals expansion. It cannot be represented by an integers ratio and foes forever. Otherwise known as infinite decimals. There’s no exact value, seeing as the number does not end.
Height:. Height is a measure of a polygon or solid figure, taken as a perpendicular from the base of the figure.
