WebThe ratio of the circumference to the diameter of any circle is a constant known as pi (π), which is equal to approximately 3.14159. From this relationship, we can derive the formula for the circumference of a circle: C = πd. where C is the circumference and d is the diameter of the circle. Using radius instead of diameter, the formula is: C ... WebA good way to quickly estimate the circumference and area of a circle is to round Pi off to the whole number ‘3’ (instead of using two decimal digits like 3.14). Use Pi = 3 to estimate the circumference and area of each of the circles below. Estimating Circumference and Area. CCA 1. 1 5 m 2 1 in. 4 4 ft 3 2 cm. 6 6 yd 5 10 m.
