Apart from the MCG, there are several other stadiums around Australia where Football is played. a and b are measured from the center, so they are like "radius" measures. A circle is a special case of an ellipse where the minor and major axes (a and b in the figure below) are equal. Calculate the circumference of an ellispe that has a major axis of 24 inches and a minor axis of 18 inches. From this relationship, we can derive the formula for the circumference of a circle: C = d This tells us that the circumference of the circle is three "and a bit" times as long as the diameter. Some people complain that the extra metres can give one team an unfair advantage. In this problem, we were given the diameter of a circle and asked to find its circumference. This can be modified to ensure all players participate. Circumference formula The ratio of the circumference to the diameter of any circle is a constant known as pi (), which is equal to approximately 3.14159.
