In a circle which ratio is equivalent to π
WebWe know that the diameter of a circle is twice the radius. The proportion between the circumference of a circle and its diameter is equal to the value of Pi (π). Hence, we say that this proportion is the definition of the constant π. (i.e) C= 2πr C= πd (As, d = 2r) The best-known approximations to π dating before the Common Era were accurate to two decimal places; this was improved upon in Chinese mathematics in particular by the mid-first millennium, to an accuracy of seven decimal places. After this, no further progress was made until the late medieval period.
